A comfortable retirement works out cheaper in Mauritius — around £2,100/month for a couple, versus £2,500 in Japan (about 16% more).

Indicative monthly estimates for a couple — real costs vary by location, lifestyle and exchange rates.
Japan: Foreigners have the same rights as Japanese nationals and can buy land, houses and apartments freehold, with no residency or visa requirement. From April 2026 buyers must disclose nationality at registration (a record-keeping step, not a restriction), and a small number of plots near defence sites can be reviewed.
Mauritius: Non-citizens buy mainly through government-approved schemes such as the Property Development Scheme (PDS), IRS and RES, or in ground-plus-two apartment developments, where they can own freehold. A qualifying purchase above set price thresholds can also confer residence. Buying ordinary land outside these schemes generally requires special approval.
Japan: Japan has no dedicated retirement visa. Self-funded retirees typically use a long-term 'Designated Activities' stay, broadly needing substantial savings (around ¥30 million) or steady pension income of roughly ¥250,000 a month; spouse and family routes are also common.
Mauritius: Those aged 50+ can apply for a Retired Non-Citizen residence permit by undertaking to transfer around USD 2,000 a month into a local account; buying a qualifying scheme property can also grant residence for as long as it is held.
Japan: Healthcare is excellent and universal — residents on a long-stay visa enrol in National Health Insurance, paying income-based premiums and then about 30% of costs (less for the elderly), with high-quality hospitals nationwide. Care is affordable by Western standards, though English can be limited outside the major cities.
Mauritius: Free public hospitals exist but expats use private clinics, chiefly the C-Care group (with branches at Grand Baie, Tamarin and Wellkin in Moka) plus others, offering good care in English and French, with anything highly specialised sometimes handled abroad. Private insurance is widely used and relatively affordable.
Japan: For your first five years as a Japanese tax resident you count as a 'non-permanent resident', so foreign income such as a UK pension is taxed only to the extent you remit it into Japan; after five years Japan taxes your worldwide income. Rates are progressive (national 5-45%, plus a flat ~10% local inhabitant tax), and the UK-Japan treaty helps avoid double taxation.
Mauritius: Mauritius has a flat 15% income tax and no capital-gains or inheritance tax, and a resident is taxed on foreign income only if it is remitted to Mauritius; the over-50s retirement permit needs about USD 24,000 a year of income. Take advice on remittance timing.
Japan: Four distinct seasons: hot, humid summers with a June-July rainy spell and late-summer typhoons, and cold, often snowy winters on the north and Japan Sea side. Spring cherry blossom (late March-April) and crisp autumn colour (October-November) are the best months. Extremely safe with very low crime; English is limited outside big cities and tourist areas, but they drive on the left, which is familiar for Brits, and daily life runs smoothly once you settle in.
Mauritius: Warm and tropical all year, with hot humid summers from December to March and pleasantly mild drier winters from June to September; cyclone season runs January to March. Winter is the most comfortable time. Very easy for British retirees, as English is an official language and driving is on the left as in the UK; the island is safe, stable and welcoming with a large established expat community.
Japan: Budget roughly 6-10% in one-off costs whether you're foreign or not — Japan adds no buyer surcharge for foreigners — covering agent commission (about 3% plus a fixed fee), a real-estate acquisition tax of around 3% of assessed value, registration and licence tax, stamp duty and a judicial scrivener's fee. A purchase typically completes within one to two months.
Mauritius: Foreign buyers purchase through approved schemes such as the PDS from a USD 375,000 minimum, and expect registration duty of around 5%, though from mid-2026 this is rising toward 10% for scheme purchases, so check the current rate; completion takes weeks to a few months.
Japan: Tokyo for energy, amenities and top hospitals; Fukuoka for a mild, affordable, walkable base popular with newcomers; Kyoto for culture and history; and subtropical, laid-back Okinawa — with cheap rural 'akiya' houses dotted across the countryside.
Mauritius: Grand Baie and the north for a lively expat hub, Tamarin and Black River on the west coast for a laid-back beach lifestyle, and Flic en Flac for lagoons and amenities.
