A note from Yasuhiro
I'm not a tax advisor or immigration lawyer — but having worked as an executive inside foreign companies in Japan, and having supported colleagues through their relocations, I know what questions you need to be asking and who to ask. This is a starting map, not a final answer. Always consult a qualified specialist for your specific situation.
📋 Visa & Residence
Engineer / Specialist
Most common for tech and finance professionals. Requires a bachelor's degree or 10+ years experience. Sponsored by employer.
Intra-Company Transfer
For employees transferred from a foreign parent company. Typically valid 1–3 years, renewable.
Highly Skilled Professional
Points-based system. Significant benefits including faster permanent residency (1–3 years vs. the usual 10).
Residence Card (在留カード)
Required to carry at all times. Issued at major airports on arrival. Register your address at the local ward office within 14 days of moving in.
My Number Card
Japan's national ID. Essential for tax filing, social insurance, and banking. You'll receive a My Number upon ward office registration.
💴 Tax
Income Tax Rates
Progressive 5–45% nationally. Combined with local inhabitant tax (~10%), effective marginal rates can reach 55% for high earners.
Non-Permanent Resident
For your first 5 years, some foreign income may only be taxed on the amount remitted to Japan — a significant planning opportunity.
Tax Treaties
Japan has treaties with most Western countries to avoid double taxation. The US–Japan treaty is particularly complex — seek specialist advice if you have US income.
2027 Reform
From FY2027, Japan will impose a minimum 30% effective tax on high earners. Relevant for executives with significant investment income or tower condominium holdings.
Yasuhiro's note
As a USCPA with FP&A experience, I can help you ask the right questions and understand the financial implications of your Japan assignment — even if the final advice comes from a licensed tax accountant.
🏥 Health Insurance
Employee Insurance (健保)
Most corporate expats are enrolled in their company's health insurance scheme — generally more comprehensive than the national system. Covers the employee and dependents.
Copay
Standard 30% of medical costs for working-age adults. Annual out-of-pocket is capped under the High-Cost Medical Expense System (高額療養費).
English-speaking clinics
International clinics in Minato and Shibuya cater to expats with English-speaking staff. Costs can be higher than standard Japanese hospitals.
🏛 Pension
Enrollment
All residents aged 20–59 must enroll in Japan's public pension (厚生年金 for employees). Automatic for corporate employees.
Lump-Sum Withdrawal
If you leave Japan permanently, you may be eligible for a lump-sum withdrawal (脱退一時金) of up to 5 years of contributions. Apply within 2 years of departure.
Totalization Agreements
Japan has agreements with the USA, UK, Germany and others to avoid double contributions. Worth checking before you arrive.
🚗 Driving License
IDP (Short-Term)
International Driving Permits from Geneva Convention countries are valid for 1 year from entry. Carry with your original license.
Easy Conversion
Switzerland, Germany, France, Belgium, Iceland — typically requires only a written test and eye exam.
Harder Cases
USA, Canada, and some Asian countries require both written and practical tests. Allow 1–3 months. Most central Tokyo executives don't own cars — parking runs ¥40K–¥80K/month in premium areas.
🏦 Banking
Expat-Friendly Banks
SMBC Trust (Prestia) and SBI Shinsei Bank offer English-language service and are most accessible for new arrivals.
What You Need
Residence Card, My Number Card, passport, and sometimes a Japanese phone number. Some banks require 6 months of residency.
International Transfers
Wise (TransferWise) is widely used by expats. Japanese bank international wire fees are high — set up Wise before or shortly after arrival.
