Best Part-Time Jobs in Japan to Improve Your Japanese

For students living in Japan, part-time jobs serve not only as a source of income but also as an opportunity to improve Japanese language skills. The Japanese learned in textbooks and the Japanese used in real-life situations often differ significantly. Through part-time work, learners can acquire practical Japanese, including communication with customers and coworkers, as well as the use of honorific language.

This article introduces some of the most effective part-time jobs for improving Japanese language ability. It is intended as a reference for those considering starting part-time work in Japan.

Common part-time jobs in Japan include restaurants, convenience stores, supermarkets, factories, cleaning services, and warehouse work. Among these, service industry jobs are especially popular among international students and technical intern trainees.

Since service industry jobs involve frequent interaction with customers, they provide valuable opportunities to practice Japanese. At first, learners may feel nervous; however, as the same phrases are repeated over time, they gradually become natural and easy to produce. Common phrases include:

・ いらっしゃいませ(Irasshaimase: Welcome)

・ 少々お待ちください(Shōshō omachi kudasai: Please wait a moment)

・ ありがとうございました(Arigatō gozaimashita: Thank you very much)

These expressions are better acquired through consistent use in real-life situations rather than through textbooks alone. In addition, such experiences provide an excellent opportunity to learn Japanese manners and etiquette.

Japan has various family restaurant chains, such as Gusto, Saizeriya, and Denny’s. Family restaurants are one of the most popular workplaces for part-time jobs among both Japanese students and working professionals.

Duties for waitstaff include seating customers, taking orders, and serving food. Students can directly interact with local Japanese customers, which helps improve their Japanese proficiency.

The use of keigo is particularly important in this context. Waitstaff are required to use formal Japanese language. For example, expressions such as “ご注文はお決まりですか” (gochumonwa okimari desuka?: Have you decided on your order?) and “こちらでよろしいでしょうか” (kochirade yoroshideshoka?: Would this be alright?) may seem somewhat intricate at first; however, manuals are typically provided, so employees can simply follow them. By repeatedly using the same expressions, they naturally become familiar over time.

Kitchen staff are responsible for preparing food. There are fewer opportunities to interact with customers; however, communication with coworkers is important.

Speed and efficiency are important in this role, so students can acquire concise and clear Japanese expressions such as “〇〇お願いします。” (onegaishimasu: Please order/bring 〇〇.), “あと何分ですか？” (ato nanpun desuka?: How many minutes are left?), and “先にこちらを出してください。” (sakini kochirawo dashitekudasai: Please serve this first.) Additionally, they can become familiar with the names of Japanese dishes and ingredients, making it an ideal environment for learning Japanese food culture.

Major convenience store chains in Japan include 7-Eleven, FamilyMart, and Lawson, and positions at these stores are widely sought after among international students.

Convenience store jobs involve a wide range of tasks, such as operating the cash register, stocking shelves, cleaning, and handling parcel deliveries. Although there is a lot to learn, these roles significantly help improve Japanese language ability.

At the cash register, staff use set expressions such as “温めますか？” (atatamemasuka?: Would you like this heated?), “袋はご利用になりますか？” (fukurowa goriyoni narimasuka?: Would you like a bag?), and “ポイントカードはお持ちですか？” (point card ha omochidesuka?: Do you have a point card?). Conversations with customers also involve more advanced tasks, such as age verification and handling utility bill payments. This helps develop the ability to explain things clearly.

This is a place where locals visit almost every day, and staff may become familiar with regular customers. Students can improve their Japanese proficiency while also gaining insight into Japanese society through natural, everyday conversations.

Having a part-time job at an izakaya is also popular among international students. Work usually takes place from the evening until midnight, in a lively atmosphere. Staff are required to maintain a positive attitude and use a bright, energetic voice, as there is often a lot of interaction among customers themselves.

At izakayas, workers can be exposed to practical Japanese used in authentic, everyday conversations, such as “お疲れさまです！” (otsukaresamadesu!: Good work!), “乾杯！” (kanpai!: Cheers!), and “ラストオーダーです” (Last order desu: Last order!). They also interact with a wide range of customers, from young people to the elderly, providing opportunities to communicate with various types of people and develop the ability to adjust their speech depending on the situation and the person they are speaking to.

However, busy hours can be very demanding, requiring both speed and teamwork, while also providing valuable opportunities to significantly improve communication skills in Japanese.

There are a wide variety of part-time jobs in Japan, and service industry roles, in particular, provide international students with valuable opportunities to engage in conversation in Japanese, thereby enhancing their language proficiency. Through working in settings such as family restaurants, convenience stores, and izakayas, students are able to acquire practical, everyday Japanese used by native speakers.

I have also personally held several part-time jobs as a student, including sorting mail at a post office, inspecting goods for supermarket delivery at a factory, working as a bookstore clerk, assisting in a sporting goods section, serving customers at a department store membership counter, supporting food production at a factory, performing data entry for an insurance company, handling medical billing data entry at a hospital, and working as a museum staff member.

When I first started working part-time, I struggled with speaking smoothly and listening comprehension. However, by repeatedly using certain phrases, I gradually gained confidence.

Part-time work provides an excellent opportunity to learn Japanese while working. If the opportunity arises, it is highly recommended to give it a try.

Part-time work is not only a source of income but also a place where Japanese is used in real-life situations. However, acquiring proper grammar and vocabulary remains essential. Reviewing the Japanese encountered at work and organizing it helps learners gain greater confidence. Studying the fundamentals at a Japanese language school while applying them in part-time work creates a cycle that leads to more effective Japanese improvement.

For those who wish to study Japanese more seriously, why not consider learning at TCJ? By using expressions learned in class at part-time jobs, and reviewing the words learned at work in class, Japanese proficiency can be significantly improved.

To enrich your daily life in Japan, it is important to prioritize maintaining a good balance between study and work. Part-time work is not only a job for earning money, but also a “classroom” where Japanese is actively used.

We hope you find a part-time job that best suits you and helps improve your Japanese skills. If you wish to aim for an even higher level, please consider joining us at TCJ.
