How to Make Your Employer Enroll You in Shakai Hoken Now

Information current as of March 2026 based on the Japan Pension Service, the Ministry of Health, Labour and Welfare, and English-language municipal guidance.

If you searched 'employer won't enroll shakai hoken,' you are probably not looking for a basic insurance explainer. You are already working, maybe already on probation, maybe already paying out of pocket at clinics, and you need the fastest legal route to make the company stop stalling.

I once worked below minimum wage in the UK simply because I did not know my rights as a foreign worker. I also work in legal affairs in Japan now, so I wrote this as a short escalation checklist, not a theory lesson. Many workers land here after googling phrases like 'probation no shakai hoken Japan' or panicking because they realize they are not enrolled in social insurance in Japan at all.

Check if your job legally qualifies for shakai hoken

Start here, because some employers bluff, but some jobs really do fall outside employee insurance. This guide assumes you are working as an employee, not running a genuinely independent business on your own.

• According to the Japan Pension Service English pamphlet, all HOJIN corporations with at least one worker are mandatorily covered workplaces. That includes the typical incorporated company structure many foreign workers see, such as a KK or GK.
• The same pamphlet says certain individual businesses become covered at five regular workers. It also notes exceptions for some individual sectors such as service, agriculture, forestry, fishing, and livestock.
• Regular employees are covered, and part-time workers are also covered if their scheduled hours and days are at least three-quarters of a comparable regular employee at the same workplace.
• Even if you are below that three-quarter threshold, the JPS easy-Japanese guide and MHLW coverage-expansion site say many short-hours workers are still included if they work 20 hours or more per week, are expected to work more than 2 months, earn 88,000 yen or more per month, are not students except limited cases, and work for a company covered by the expanded rules.
• The JPS pamphlet is explicit that nationality does not matter and that a worker who meets the criteria is insured from the start of probation. It also says worker consent or contract wording does not override mandatory coverage.
• A rare exception exists for some temporary overseas assignees under a social security agreement. If your employer says this applies to you, ask to see the actual certificate, not just a verbal excuse.

Fast rule of thumb: if you are a regular employee at a corporation, or a short-hours worker meeting the current thresholds at a covered company, you should treat 'wait until after probation' as a red flag and start documenting immediately.

The 3 excuses employers use and what the rules say

This is where most of the stalling happens. In practice, the excuse is usually about money, because the JPS guide says the contribution is evenly shared by employer and worker.

1) 'Probation means no shakai hoken.'

This is the most common one, and the official rule is the clearest. The JPS pamphlet states that a worker who meets the enrollment criteria is insured from the start of probation.

2) 'You are foreign, on a visa, or your contract says no.'

Also false for eligible workers. The same official JPS material says that workers are covered regardless of nationality, and that the rule applies irrespective of contract wording or worker consent.

3) 'You are part-time, or our company is too small.'

This one is only sometimes true. Use the thresholds above, not the boss's opinion. Since the 2024 expansion explained by MHLW, many workers who were previously pushed out of shakai hoken are now squarely inside it.

These excuses are common enough that foreign residents keep posting about them online. Individual experiences vary, and the official sources above should control.

One foreign resident wrote in a Reddit thread: 'I was told I had to pay my own health and pension for the first 3 months (as I was on probation).'

Another worker posted on Reddit: 'At the moment, I have no company-sponsored health or social insurance ... even if I'm in the probationary period.'

What to do this week if your employer still will not enroll you

If the company is still stalling, stop arguing verbally and switch to a paper trail. Your goal this week is simple: prove eligibility, create written evidence, contact JPS, and avoid being left uninsured.

1. Today: gather proof.
   • Your contract or offer letter showing job title, hours, start date, and any probation clause
   • Your latest payslips and bank salary records
   • Your roster, timesheets, or shift screenshots showing actual weekly hours
   • Your residence card, My Number, and Basic Pension Number if you have one
   • Any email, chat, or message where the company said it would wait, refuse, or 'exempt' you
2. Send one written demand to HR or the owner.

   Do not keep this at the level of hallway conversations. Ask for enrollment in writing and ask them to file using your actual employment start date. Useful phrases:

   • 社会保険の加入手続きをお願いします。 (Shakai hoken no kanyuu tetsuzuki o onegaishimasu.) — I am asking you to complete my social insurance enrollment procedure.
   • 社会保険の加入条件に当てはまると思います。入社日で資格取得届を提出してください。 (Shakai hoken no kanyuu joken ni atehamaru to omoimasu. Nyuushabi de shikaku shutoku todoke o teishutsu shite kudasai.) — I believe I meet the social insurance criteria. Please submit the enrollment form using my employment start date.

   Ask for a reply by a specific date, such as two or three business days, and ask for a copy or screenshot of the filing once it is submitted.

3. Escalate to the Japan Pension Service.

   If there is no firm answer, go straight to the Japan Pension Service shakai hoken route in English. The JPS multilingual consultation page says workers and employers can use the EPI/EHI procedure line at 0570-007-123, and you can also find your nearest branch office here. Useful phrase:

   • 会社が社会保険に入れてくれません。加入条件に当てはまるか確認したいです。 (Kaisha ga shakai hoken ni irete kuremasen. Kanyuu joken ni atehamaru ka kakunin shitai desu.) — My company is not enrolling me in social insurance. I want to confirm whether I meet the criteria.

   If this feels overwhelming, that's exactly why I built LO-PAL — you can post your question for free and get answers from local Japanese people who know your area. If you need hands-on help calling the pension office, translating a message to HR, or going to city hall, you can also request a task, and you only pay when the job is done.

   This step matters because JPS publishes both its first registration request and its reminder letter to employers, and the reminder letter says JPS may visit and investigate the workplace. Escalation is not rude here; it is exactly what the system expects when an employer will not comply.

4. If you have no active workplace health insurance right now, protect yourself at city hall.

   Yokohama City's English guidance says anyone who is not signed up for employee health insurance through their workplace must join National Health Insurance, and Osaka City's English procedure page says to apply within 14 days of becoming eligible. If you are age 20 to 59 and are not in Employees' Pension, ask about National Pension at the same visit.

   • 職場の社会保険に入っていないので、国民健康保険に入りたいです。 (Shokuba no shakai hoken ni haitte inai node, kokumin kenko hoken ni hairitai desu.) — I am not enrolled in workplace social insurance, so I want to join National Health Insurance.

   This fallback does not let the employer off the hook. It just keeps you covered while the employer problem is being fixed.

5. If the company threatens you, cuts shifts, or withholds documents, call the labour side too.

   The MHLW Telephone Consultation Service for Foreign Workers gives advice in 13 languages, and the Labour Standards Advice Hotline covers evenings and weekends. These services do not replace JPS for enrollment checks, but they are useful if the dispute turns into retaliation or a wider working-conditions problem.

   • 相談したいです。社会保険に入れてもらえず、困っています。 (Soudan shitai desu. Shakai hoken ni irete moraezu, komatte imasu.) — I need advice. My employer will not enroll me in social insurance, and I am having trouble.

Who to contact in English and how to protect your record

Once you start escalating, the goal is simple: keep yourself insured and make your paper trail stronger than the employer's excuses.

• Japan Pension Service: use 0570-007-123 or visit a branch office. The JPS consultation page says free interpretation is available in English, Chinese, Korean, Portuguese, Spanish, Filipino, Vietnamese, Indonesian, Thai, Nepali, and Burmese, though phone charges still apply.
• MHLW foreign worker line: English is 0570-001-701, Monday to Friday, 10:00 a.m. to 3:00 p.m., closed noon to 1:00 p.m., with call charges listed on the official page.
• Labour Standards Advice Hotline: English is 0120-531-401. The official hotline page says it is free, anonymous, and available when regular offices are closed.
• City or ward office: if you are not enrolled in employee insurance, go to the National Health Insurance counter and ask how to keep coverage active until the employer issue is corrected.

• Keep copies of your contract, probation clause, payslips, bank records, schedule, and all company messages in one folder.
• After every call or office visit, write down the date, office name, staff name, and what you were told.
• If you already have a Basic Pension Number Notice, keep it safe. JPS says that number does not change, and a branch office can reissue the notice if you lose it.
• If city hall enrolls you in NHI now and your employer later fixes shakai hoken, go back promptly. Osaka City's English guide says people who become enrolled in employee health insurance should discontinue NHI within 14 days.

Bottom line: if you qualify, you do not need your employer's permission to know the rule. You need a written demand, a JPS contact, and a same-week backup plan so you are not left uninsured.
