Japan has the highest cremation rate in the world — above 99.9% of deaths in Japan are cremated, by law or strong social convention depending on the municipality. This single fact is the most important thing a British family needs to understand when a death occurs in Japan: if you do not act quickly to prevent automatic local cremation, the body may be cremated before repatriation arrangements are made.
This is not malicious. It reflects Japanese cultural and legal norms. But it has implications that families in the UK are often not prepared for.
The cremation default
Under Japanese law (the Graveyards and Burials Act), burial in the ground requires special permission and a designated burial ground. In practice, nearly all deaths in Japan result in cremation. Hospitals and local municipal authorities expect cremation. A funeral home, on receiving a body, will proceed on the assumption that cremation is the intended outcome unless told otherwise.
For British nationals who wish to be repatriated to the UK for a full-body burial or cremation in the UK, the family or a repatriation coordinator must explicitly communicate — in writing and promptly — that no local cremation is to take place. This instruction should go to the hospital, the local funeral home, and the British Embassy simultaneously.
Families who do wish to bring ashes home rather than the full body have more flexibility. Ashes repatriation from Japan is achievable and often faster than full-body repatriation. Both options are viable.
Police notification for unnatural deaths
Any sudden, unexpected, or unnatural death in Japan triggers mandatory notification to the Keisatsu (Japanese police). A police-appointed forensic physician (kansatsu-i) examines the death. If the cause of death is unclear, a judicial administrative post-mortem (gyousei kansatsu) is ordered.
Japanese police investigations are thorough. They take time. Releasing the body requires police completion of their examination and issuance of a police certificate confirming no criminal investigation is outstanding. In straightforward natural-cause deaths the police clearance is typically issued within a few days. In accident or unexplained-cause cases, this can extend to 2 to 3 weeks.
Japanese-only documentation
All Japanese official documents are in Japanese. The Japanese death certificate (Shibo Todoke-Kisai Jikou Shomeisho), police clearance, and export documentation are in Japanese only. Certified English translations are required for UK purposes: for the Coroner, for the death registration process, and for insurance purposes.
Finding certified translators for Japanese legal and medical documents is manageable in Tokyo and the main cities. In rural areas — the Japan Alps, Hokkaido, rural Kyushu — it is harder and slower.
The British Embassy
The British Embassy is in Tokyo (Ichiban-cho, Chiyoda-ku). There are British Consulates in Osaka and Fukuoka. The Embassy’s emergency line is the FCDO global number: +44 20 7008 5000. The Embassy registers the death and can provide a list of Japanese funeral directors experienced with foreign national repatriation.
Remote locations
Japan has significant tourist populations in remote areas: the Japan Alps (hiking, skiing), Hokkaido (skiing, nature tourism), the Oshika Peninsula, and rural hot spring areas. Deaths in these locations require internal transport to the nearest city before the export process can properly begin. Japan’s domestic transport infrastructure is excellent, but adding the internal transfer leg extends the timeline.
Cargo routing
Japan Airlines (JAL) and All Nippon Airways (ANA) operate direct Tokyo Narita and Tokyo Haneda to London Heathrow cargo services. British Airways operates the same route. These direct connections mean the cargo leg is among the most straightforward in Asia once documentation is complete.
Timelines
Natural death, Tokyo or major city, ashes repatriation: 10 to 14 days. Full-body repatriation, natural death: 14 to 21 days. Unnatural death with police investigation: 21 to 35+ days. Remote area death: add 5 to 10 days for internal transport.
