Other info (from job posting)

Written examination and other assessments use SPI aptitude tests.

Some free-text details (such as special notes or the reason for age restrictions) may still appear in the original Japanese until an accurate translation is confirmed, since translating them out of context could distort their meaning.

Check before you apply

  • Whether your residence status permits this kind of work
  • Whether the pay, hours, and days off match your wishes
  • How to apply and what documents are needed (Hello Work may require a referral letter)
  • If applying with the Specified Skilled Worker visa: the company needs to prepare to accept SSW workers (support system, notifications, etc.). When applying or inquiring, ask whether they plan to accept SSW workers

GloJob does not judge work eligibility or visa suitability. Please make the final confirmation yourself, with the employer and a professional.

For employers: see here for information on hiring international talent and preparing to accept SSW workers → Employer page (Japanese)

Just your email address is enough to apply.

How to apply for a Hello Work job

Applying can be a bit complicated — check the steps here.

Applying for Hello Work jobs works a little differently. Check the steps below. You apply through Hello Work itself — GloJob does not apply or act as an agent for you.

Job number for this posting
13090-31782661

Search this number on the official Hello Work website to find this job.

There are three ways to apply

  1. Online self-application (from home — the easiest)

    Apply directly to the employer from your Job Seeker My Page (created with an email address). This works only for jobs marked "Online self-application: accepted." In My Page, search the job number → "Self-apply" → write your reason for applying, attach your résumé, and send. No referral letter is needed.

  2. Online referral

    Requires a Job Seeker My Page and job-seeker registration at a Hello Work office. Contact Hello Work, receive a referral online, and check the referral letter in My Page.

  3. Get a referral letter at the counter

    Visit your nearest Hello Work office, register as a job seeker and have a consultation, get a referral letter, and submit it to the employer (in person or by mail).

※ Whether "online self-application" is available differs by job. Check the "Online self-application accepted" field on the official Hello Work page.

If you're worried about Japanese (free, with interpreters)

Foreign Employment Service Centers (Tokyo, Nagoya, Osaka, Fukuoka) and foreigner corners at Hello Work offices nationwide have interpreters who help — free of charge — with writing application documents and procedures in English, Chinese, and other languages.
