Whether you're looking for a side-gig or a boost to your resume, check out these six part-time jobs for the month of June.

By 5 min read

In this first installment of our cool part-time gigs and side hustles you can do in Japan, we’ll look at an English teaching job for the Japan Self-Defense Force, an opportunity in STEM, medical Science Proofreading, localization gig for a gaming company in Tokyo and an English and Cooking Teacher in Kobe.

These are great ways to make money on the side or even prepare your resume for a switch in careers.

1. English and Cooking Teacher

Enjoy cooking and live near Kobe? How about teaching a relaxed English class with cooking as the centerpiece right in the heart of Kansai?

This neat little opportunity will pair your love of cooking with your English skills for a part-time gig as a kitchen-based English teacher for Kobe-based Cooking Talk.

You’ll use cooking as a tool to share English with students interested in cooking. Classes are held in the downtown Sannomiya area, and transportation costs are included up to ¥1000 per day, covering most teachers living just outside the city.

  • Company: Cooking Talk
  • Salary: ¥1,600 ~ ¥2,500 / Hour
  • Location: Hyogo, Japan
  • English: Fluent
  • Application: Must currently reside in Japan.

2. Game localization tester

Digital Hearts is a leading provider of localization services to the gaming and publishing market and is looking for part-time localizers. Here’s what you’ll need to throw your hat in the ring:

Conversational Japanese (N2 recommended) and native fluency in either English, German, French, Italian or (European) Spanish
Have a current residence in the Kanto area and visa status that allows for this type of work
A love of gaming and a sincere interest in the industry

You’ll be testing games produced by both major and indie outlets.

Games you’ll be testing will have already been localized to your native language. Hence, you won’t be doing deep localization. However, you will be providing feedback about any linguistic oddities you run into while playing, as well as any technical issues that might crop up while you’re in the game.

You’ll be testing games produced by both major and indie outlets. Depending on your current and future skill sets, there may be opportunities to interact on-site with the game developer teams whose products you end up testing. Pretty cool, right?

Suppose you have prior game translation and/or localization experience. In that case, you may find yourself at a bit of an advantage in applying, and the same goes for any experience with QA or product testing. Verbal and written fluency in Japanese (business emailing skills, equivalent to N1) is also preferred, but as stated above, not required.

It’s an excellent opportunity to help spread medical research beyond the borders of Japan. Certain aspects of the position are negotiable based on experience, so don’t be shy when discussing your experience in the profession.
