Japan is one of Asia’s most rewarding postings for UK professionals, combining very high safety, excellent food, strong career opportunities in finance, technology, and manufacturing, and a 2021 bilateral social security agreement that coordinates NI contributions between the two countries. Around 15,000 UK nationals live there. Tokyo is an expensive city by Asian standards — particularly for international school fees — but outside Tokyo costs drop substantially. The UK State Pension is uprated while you live in Japan under the 2021 SSA.

The UK–Japan SSA and the State Pension — the bottom line
The UK–Japan Social Security Agreement (2021) provides for NI totalisation: you pay social insurance in one country only, avoiding double contributions. Under the SSA, the UK State Pension is uprated annually while you live in Japan — unlike in Australia, New Zealand, or Canada where it is frozen. You should confirm your specific uprating position with HMRC or a specialist adviser, as bilateral (non-EEA) agreement terms can have nuances.
International school fees are the single largest variable cost for families in Tokyo. Most senior finance, legal, and multinational employers include a school-fee allowance in Tokyo expat packages — confirm what is covered before accepting an offer. Use our projection tools to model Japanese income tax, nenkin contributions, voluntary UK NI, uprated State Pension, and long-term wealth projections together. Take advice from a regulated financial adviser with UK–Japan cross-border expertise: the UK–Japan DTA, ISA treatment while Japan-resident, and nenkin withdrawal planning all require specialist input.
