The COVID-19 pandemic has brought a pause to the international tourism industry all over the world. As various factors signal an end to the pandemic and the tourism industry slowly recovers, consumers with repressed travel desires are contributing to the explosive growth in tourism. While the return of tourists may be welcomed by most destinations as they make up for losses suffered during the pandemic, the consequences of tourism growth may also lead to popular locations facing overtourism and challenges in managing them sustainably.

Inbound tourism to Japan plays an important role in revitalizing the nation's economy. As Japan welcomed 3.08 million foreign tourists in March 2024, the latest record smashed the previous high of 2.99 million visitors from July 2019. Based on the latest data, each tourist has spent an average of 210,000 yen per holiday, bringing in a total of 5.3 trillion yen in revenue in 2023. In addition to this revenue, this increased tourist expenditure can bring infrastructural developments to the region. With the growth in demand for tourism products, the government foresees an increase in employment opportunities as regions overcome labor shortages through the integration of digital technology to enhance tourism services. The rise of new tourism formats such as eco-tourism and food tourism has helped to promote the charm of lesser-known places, contributing to the prevention of young people leaving rural areas. With the merits above, the government is hopeful that the goal of receiving 32 million annual foreign visitors can be achieved by 2025.

However, there are challenges and voices of disapproval regarding various aspects. The current capacity and infrastructure in tourist destinations are unable to keep up with the growth of visitors to Japan. Local officials and businesses have had to come up with new strategies to limit the number of tourists entering the attractions to maintain natural ecosystems and prevent negative impacts on local cultural heritage. Furthermore, the revival of tourism has affected the quality of life of residents living in famous tourist destinations. For example, Kyoto City has limited the entrance of tourists into the Gion district after incidents of geishas being aggressively approached by tourists for photos. The excessive number of tourists taking photos around the railroad of a local station at Kamakura ends up causing interference to road traffic and the daily commute of residents.

The tourism industry has the potential to re-energize a nation's economy after the recession brought about by the pandemic. However, it is also important for the government to strike a balance between ensuring the sustainable development of the tourism industry and maintaining the quality of local residents' lives. Tourism growth needs to be done without compromising the social, cultural and environmental aspects of the country.

Do you agree or disagree with the Japanese government's push for more inbound tourism?
本文由来オリジナル
Sample 1(賛成・94語)
I agree that an increase in tourist numbers to Japan has the potential to provide a significant boost to the economy. An increase in international visitors would result in greater revenue for the hospitality sector. This would result in the creation of new employment opportunities and economic prospects. Greater cultural exchange between Japanese hosts and foreign guests can also foster mutual understanding and goodwill, which in turn can lead to more favorable perceptions of Japan. Therefore, I believe that more inbound tourism can be a significant boon for Japan's economy and global reputation.

Sample 2(反対・84語)
I think too much tourism is not good for Japan. Japan is already crowded enough without any tourists, and increasing the number of people in this already crowded environment would strain infrastructure such as transportation and waste disposal. This could negatively influence the environment and harm natural sustainability. In addition, the stress caused by the actions of inconsiderate visitors could easily imbalance local residents' peace of mind and disrupt local neighborhood traditions. Therefore, I think tourism should be regulated so as to prevent overtourism.

📖 本文(2024)全文

The Japanese publishing industry has been going through difficult times for the past few decades. Sales in the industry have declined since 1996, when the figure reached its peak, as the internet and smartphones took over much of the place that books and magazines previously held. Magazines have suffered more than books, because web-based media and SNS are more effective in terms of providing timely information or connecting people with the same interests, both of which were primary functions of paper magazines. According to the statistics, the total sales of the publishing industry in 2021 were only 63% of what they were twenty-five years ago.

One promising option for the industry is e-publishing. In early 2010, Amazon launched the first e-reader to support Japanese-language PDFs, immediately followed by Apple's first iPad. These innovative devices encouraged publishers to offer digitized versions of their books: e-books. The latest statistics show that the share of e-books to total publication sales is now over 30% and is expected to grow.

There are a number of advantages to e-books. First, they cost less to produce, so the prices are generally cheaper compared to their paper counterparts. Second, they do not take up as much space as paper books. You can buy hundreds of e-books and read them on a tablet or an e-reader, with no need to keep bookshelves in your home. Third, e-books are believed to be more environmentally friendly, or "green." Since they are not made of paper, e-books do not consume forest resources.

Some people, however, point out potential problems e-books have. If you buy a paper book, for instance, the book stays with you unless you get rid of it, but in some cases e-books you purchased may become inaccessible when the publisher goes out of business. Also, e-books may not be as environmentally friendly as you might think. E-readers require a lot of energy, chemicals, rare metals, and water to produce. In addition, maintaining online platforms for e-books is energy-intensive, consuming fossil fuels and contributing to global climate change. Thus, whether e-books are the smarter choice remains debatable.

✏️ 問題・解答・分析
A 穴埋め ①②③
The internet and smartphones have had more negative influence on the ① sales of magazines than those of ② books. They provide a more effective way of helping people who ③ share the same / have similar interests to connect with each other.

Replacing paper schoolbooks with online e-books for environmental reasons — good idea?
本文由来オリジナル
Sample(賛成・94語)
I think it is a good idea to replace paper schoolbooks with online e-books. Since e-books do not require tree-originated resources to produce, using them instead of paper books will protect forests. As the news from Japan and many parts of the world show, global warming is worsening at an alarming rate. By conserving forests, we can protect their ability to absorb carbon dioxide, which is vital in slowing climate change. Because of the large number of schoolchildren, changing their textbooks to e-books will have a great impact in reducing the consumption of trees.

📖 本文(2023)全文

Today, sushi is very popular and eaten all over the world, from high-end restaurants in New York City to street markets in Morocco. It tends to be favored as healthy food and its aesthetic quality often fascinates people. Despite the common belief that sushi is a traditional dish in Japan, it has been historically transformed through cultural adaptation to the present.

When asked which country sushi comes from, one would instantly respond "Japan". However, sushi was first eaten in Southeast Asia over 1600 years ago and was called Narezushi, pickled fish with salt and rice. Hundreds of years later, sushi arrived in Japan and was slowly adapted over the centuries. It was not until the 1820s that the Edo style sushi was created using fresh fish and rice vinegar, and from there, in the 1970s, sushi became modernized and more widespread across Japan with the advancement of refrigeration. Yet, credit for this now international dish is only given to the Japanese with its roots forgotten.

When Japanese people travel abroad, many have the opinion that sushi is not authentic. For instance, many Japanese might consider the American tuna roll with cream cheese, Jalapenos, and a spicy southwestern sauce not to be proper sushi. Also, some might take issue that sushi is often prepared by untrained cooks in America whereas in Japan it is an artisan skill developed over a lifetime. However, sushi in America has been changing since the 19th century. Similar to how sushi was adapted to the flavor profiles of the Japanese, the same can be said for America.

Sushi is not the only cuisine that has been adopted from other cultures over the past 100 years. One example is taco rice, which was created in Okinawa but was heavily influenced by Tex-Mex cuisine. After World War II, with the occupation of allied forces in Okinawa, there was a demand for tacos, which requires ground corn to make flatbread to wrap meat and vegetables. However, because there was a lack of ingredients to make traditional Tex-Mex cuisine, a local restaurant owner adapted the recipe to use more Japanese ingredients, chiefly rice. Nowadays, when many Japanese think of taco rice, they only relate it to Okinawa instead of the American southwest or Mexico. This is because it has been made into something uniquely Japanese, similar to how Jalapeno sushi in the U.S. is uniquely American.

While American sushi restaurants might sell traditional Japanese sushi, it is currently diverging away from Japanese traditions, just as modern sushi was adapted from Narezushi. However, it remains to be asked whether American sushi will ever be accepted as its own cuisine or will always be labeled inauthentic.

✏️ 問題・解答・分析
A 穴埋め ①
According to the fourth paragraph, when taco rice was first created, it was almost impossible to cook tacos in Okinawa because ① there were no local ingredients available to cook tacos as traditional Tex-Mex cuisine, yet a restaurant owner managed to create taco rice by using Japanese rice.
• "lack of ingredients" → "no local ingredients available" パラフレーズ "ingredients" は借用可。"lack of"→"no...available" は言い換え。
• "to make" → "to cook tacos as" パラフレーズ "make"→"cook" 同義語置換+具体化。
• "traditional Tex-Mex cuisine" 直接借用可 固有名詞的表現。

B 穴埋め ②③
In the second paragraph, the author explains ② the roots of sushi and how it has been historically changed, becoming more widespread as technology developed. In the third paragraph, the author suggests that American sushi has its own history and culture although there are some people who ③ do not consider it authentic.
②: "roots" は本文から借用可。段落全体→「寿司の起源」と要約するスキルが必要。 語借用可 要約
③: "not to be proper sushi" → "do not consider it authentic" パラフレーズ
"proper"→"authentic" の同義語置換。第5段落 "inauthentic" からも着想可能。

Is the influence of foreign food culture on traditional dishes a good or bad thing?
本文由来オリジナル
A1(良い・82語)
I think the influence of foreign culture on traditional dishes is beneficial. I prefer culturally adapted dishes such as American sushi to traditional dishes. American sushi is often cooked with vegetables so that it can be eaten by everyone. Also, some people may not like or cannot eat raw fish. It is also a good opportunity to learn what culture American people have. For example, avocado sushi tells us that American people are used to eating avocado with rice and soy sauce.
活用度: 低 — アメリカ寿司という話題のみ本文由来。具体例はすべてオリジナル
A2(悪い・97語)
Although trying culturally adapted food can be interesting, it is more important to protect traditional food culture. If many people eat culturally adapted food, those who cook dishes in a traditional way may lose their job. To make matters worse, it is difficult to regain tradition once it is lost. In addition, foods made traditionally are likely to be healthier. For example, soy sauce made and sold in some foreign countries may be more likely to have additives, which makes it unhealthy and taste less authentic. Therefore, I think the influence of foreign cuisine is a disadvantage.

📖 本文(2022)全文

Machine translation is the process by which computer software is used to translate text in one language to text in another language. In recent years, this software has become available online and free to use. Google Translate is perhaps the most famous example of machine translation software, but there are many others available online and integrated into computers and mobile devices. In light of recent advancements in machine translation technology, people have begun to consider whether machine translation will replace foreign language learning in the future.

One major strength of machine translation is the ability to translate whole sentences, paragraphs, even pages of text all at once, which requires the processing of interconnected relationships between multiple words, phrases, and whole sentences within a single block of text. Machine translation software achieves this by analyzing the similarities and differences in the grammar rules of multiple languages. Another major strength is the speed of machine translation. Today, machine translation is capable of translating pages of text in mere seconds. When combined with software that recognizes human speech and automatically records it in text form, oral conversation can also be translated in real time. Whether in an office, or walking outside, machine translation can potentially eliminate the need for foreign language skills.

However, despite the potential of machine translation, translated texts still have many errors. The longer and more complex the sentence is, the higher the chance for errors. In addition, professional human translators argue that machines cannot understand culture and situations of communication, which are closely connected to language. For example, the Japanese word sumimasen is often translated to "I'm sorry" in English. But, sumimasen has a special cultural meaning in Japan and could also mean "thank you." If someone receives a gift or an act of kindness, replying "sumimasen" does not mean "I'm sorry." In this case, the meaning is closer to "thank you," and this is due to Japanese culture and communication situation. Such complications cause inaccuracies in machine translation. Intended use of the translation is also a problematic factor for machine translation. For example, machine translation software cannot tell the difference between the appropriate sentences needed in a business email and those needed in an academic essay. The human brain should be respected because it can understand these things. That is why many people say that human language learning will never be replaced by machine translation.

While it is certainly true that machine translation will not replace foreign language learning today, it is improving daily. The shortcomings of machine translation listed above may eventually be overcome by technological advances. Artificial intelligence programs get smarter every day by continuously gathering and analyzing samples of language from newspapers, books, blogs and streaming videos all over the world. Some people believe that machines will eventually become smart enough to master languages. However, others feel that there are parts of language and communication that can only ever be understood by humans.

✏️ 問題・解答・分析
A 穴埋め ①②
In the first paragraph, the author introduces the main topic of the passage, which is whether machine translation will make ① foreign language learning unnecessary / obsolete in the future. In the second paragraph, the author discusses two ② major strengths of machine translation.
①: "replace foreign language learning" → "make foreign language learning unnecessary/obsolete" 高度なパラフレーズ
"foreign language learning" はそのまま借用。"replace" → "make...unnecessary" が核心の変換。

②: "One/Another major strength" → "two major strengths" 直接借用可
段落構造を「two」と数える読解力+単数→複数のみ。

B 穴埋め ③
In the third paragraph, sumimasen is mentioned as an example to illustrate machine translation's shortcomings, namely ③ difficulty in translating words which have special cultural meaning / inability to understand culture and situations of communication.
③(2パターン):
A: "cannot understand"→"difficulty in translating" + "culture and situations"→"special cultural meaning" 完全パラフレーズ
B: "cannot"→"inability to understand" + "culture and situations of communication"そのまま 品詞変換 借用多
どちらでも正解。求められるスキルレベルが大きく異なる。

Suppose machine translation overcomes all weaknesses. Will humans continue to study foreign languages?
本文由来オリジナル
A1(続ける・99語)
I think humans will continue to study foreign languages. There are two fundamental reasons. First, language is connected to human culture and a natural part of human existence. So, the desire to speak different languages will not disappear even though superb machine translation is available. Second, by acquiring multiple languages, humans can recognize multiple ways of grasping the world, which is beneficial to human brains. Due to convenience, it may be that some people will choose not to study foreign languages. Nevertheless, it is my belief that foreign language study will survive any technological advances.
活用度: 低 — 言語と文化の結びつきのみ第3段落から。他はオリジナル
A2(続けない・99語)
I don't think humans will continue to study foreign languages. Firstly, it is difficult to learn grammar and tens of thousands of vocabulary words. If people can choose to skip years of difficult study, they will. Another reason is competition. As a student, if I spend my time learning foreign languages, I will fall behind others who train abilities that AI cannot copy. They will match my skills with AI, but I cannot match theirs. Some may wish to learn foreign languages for recreation or mental exercise, but for most situations, machine translation will make foreign language study obsolete.

📖 本文(2021)全文

There is an ongoing debate about whether students should be required to study subjects that are considered part of the "liberal arts." The liberal arts are university subjects that include history, philosophy, foreign languages, music, and so forth. A liberal arts education exposes students to a range of different subjects and seeks to cultivate students' critical thinking and reasoning skills. These are not the most practical subjects, but by exposing students to different ideas through liberal arts classes, supporters of the liberal arts believe that students will develop a more balanced skillset that will allow them to pursue different careers in the future.

However, in today's increasingly specialized world, many people question the validity of such an education. A liberal arts education is often compared to more practical majors, such as business, engineering, or computer programming. These specialized and more practical majors explicitly seek to cultivate students' skills in these fields and prepare them for jobs in industries related to their majors. By majoring in a field such as finance, for example, students can be expected to be best prepared to obtain jobs in the financial industry. This is because they will have specialized and detailed knowledge of finance and will hypothetically not require much time to learn how to perform the duties of their future jobs.

One can expect that in today's data-driven and technical work environment, a specialized major would be better for most students. However, the evidence is far from conclusive. Many successful people received a liberal arts education and they have been able to translate the skills learned from their liberal arts curriculum into success in many specialized fields. For example, Peter Thiel, co-founder of PayPal and a successful technology entrepreneur, majored in philosophy at Stanford University. Jack Ma, billionaire and founder of Alibaba Group, majored in English. Susan Wojcicki, CEO of YouTube, majored in history.

It is thus clear that a liberal arts education will definitely not prevent one from entering a more specialized field. But is it truly advantageous? Would it serve students best to avoid a liberal arts education and instead focus on a specialized one? The debate continues, but we should be able to obtain a clearer answer to this question in the near future.

✏️ 問題・解答・分析
A 穴埋め ①
Even though liberal arts subjects are not practical, they are very useful in making a career decision because students can ① develop a more balanced ability to pursue various occupations by studying them.

Which should be more important: liberal arts or practical majors?
本文由来オリジナル
解答例1(実学・100語)
I think practical majors are more important. Students who study liberal arts will be disadvantaged when they apply for jobs requiring them to compete with others. Many bosses prefer to hire a financial analyst who studied finance or economics over someone who studied philosophy or history. Furthermore, in the future this issue will become worse. In the past, there were not as many specialized fields as there are today. Studying liberal arts did not disadvantage students, but today not having technical skills is a serious problem when searching for jobs. Therefore, studying a more practical field is the better option.
活用度: 中 — 就職の不利・金融の例は本文第2段落から転用。専門分野増加・技術スキル不足はオリジナル
解答例2(教養・81語)
In the near future, I think liberal arts subjects will become more important. After graduation from university and getting a job, there will be enough opportunities to study more practical skills. However, you will probably not have much time to study liberal arts while working. Another reason is that knowledge of specialized subjects is often not useful enough to succeed in the world of business. Therefore, it is desirable to obtain more balanced knowledge by studying liberal arts subjects in college.
