UK Mortgages for British Expats in Japan

Who this page is for

If you are a British national living and working in Japan and you want a UK mortgage, this page is for you. Common situations we see:

• A British national working in finance, banking, or asset management in Tokyo, often for a global investment bank, hedge fund, or asset manager.
• A British national working in tech for a Japan-based subsidiary of a major employer (Google Japan, Meta, Amazon, Apple, Microsoft) or a Japanese tech company.
• A British national working as a translator, consultant, or in international media.
• A British national teaching English (JET, eikaiwa, university) on a more modest salary.
• A British national married to a Japanese citizen and living in Japan long-term.
• A British national who has built a career in Japan over many years and is now looking at UK property as an investment or future home.

Japan has a long-established British expat community concentrated in Tokyo. Cases vary widely by employer profile and income level.

What UK lenders think of Japan

Japan sits firmly in the lender comfort zone. Stable economy, mature banking, transparent tax reporting. Around 10-12 expat lenders lend to Japan-resident British nationals.

Where Japan varies:

• Tokyo finance and tech employees: cleanest profile, well-understood employers.
• English teachers and lower-paid roles: smaller income base, deposit-driven cases.
• Long-tenured Japan residents: often strong deposits accumulated, sometimes with permanent residency.

How Japanese yen income is treated

Japanese yen (JPY) is treated as hard currency by all expat lenders. The standard 20 percent haircut applies at most lenders. A handful of specialist lenders apply no haircut to JPY income.

Tokyo finance compensation is often heavily bonus-weighted. Some lenders include bonus in affordability with a discount; others exclude it. For finance roles where bonus is 30-50 percent of total comp, lender selection on this point can swing maximum borrowing materially.

The Tokyo finance employer angle

A large share of British expats in Japan work in Tokyo finance. Major employers (Goldman Sachs, Morgan Stanley, JPMorgan, Citi, Nomura, MUFG, SMBC) are well-known to UK lenders and underwrite cleanly. The case structure usually centres on:

• Base salary (well-understood, included in full).
• Cash bonus (treated variably by lender).
• Stock-based compensation, RSUs (treated variably, often with a discount).
• Allowances (housing, schooling) - typically excluded from affordability but useful for deposit.

The Tokyo tech employer angle

Tech sector cases are similar in structure to finance. Major employer profiles (Google, Meta, Amazon, Apple) are well-known. Stock comp is often a meaningful portion of total comp and the lender treatment determines case strength.

Deposit and rates

Deposits for British expats in Japan typically sit at 25-30 percent. Strong finance and tech employer profiles access the lower end. Lower-income profiles or longer-tenured Japan residents may need 30-35 percent.

Expat rates from Japan are typically 0.3 to 0.6 percent above the equivalent UK-resident product.

Common situations from Japan

Tokyo investment bank or asset manager. Common high-income profile. Strong employer, substantial bonus and stock comp. Lender selection on bonus and stock treatment is critical. Deposits 25-30 percent.

Tokyo tech employee on stock-heavy package. Similar profile to finance with a different income mix. Same lender selection considerations.

Long-tenured Japan resident with permanent residency. Often a different case profile - long employment history, accumulated deposit, sometimes a different employer than the original move-out reason. Cleanest cases when deposit is strong.

English teacher on modest salary. More deposit-driven case. Smaller income, lender pool tighter, but workable with good deposit and stable employment.

Returning to the UK from Japan. Common after several years in finance or tech. Apply 3-4 months before the move. Income source switches from JPY to GBP at the point of return.
