Sea Burial in Japan › Complete Guide

Sea Burial (Kaiyōsō) in Japan:
Legality, Cost & How It Works

Everything families ask us before entrusting a loved one to the sea — the legal rules, what actually happens aboard the vessel, what it costs, and how to arrange it from Japan or from overseas.

Ask us in English — free consultation
In short. Sea burial (kaiyōsō, 海洋葬) is practiced legally across Japan under national guidelines published by the Ministry of Health, Labour and Welfare in 2021: ashes must first be ground to a fine powder (under 2 mm) and scattered away from shores, fishing grounds and shipping lanes. En Co., Ltd. — a member of the Japan Sea Scattering Association — has performed more than 3,800 ceremonies off Kagoshima and Fukuoka since 2013. An unattended ceremony costs ¥54,450 tax included; attended ceremonies start at ¥148,500 (shared vessel) or ¥176,000 (private charter). Part of the ashes can always be kept as a keepsake.

Is Sea Burial Legal in Japan?

Yes — when four rules are respected. We follow all of them on every sailing.

1

Powder, not fragments

Ashes must be ground to a fine powder under 2 mm before scattering. This is the firmest rule in Japan, and powdering is included in every one of our plans — done by hand in our own facility.

2

Away from people's daily waters

Scattering takes place offshore, away from beaches, fishing grounds, aquaculture and busy sea lanes, at sea areas agreed with local operators.

3

With respect and moderation

Japan's Ministry of Justice holds that scattering ashes is not illegal when performed as a funeral rite with restraint. Flowers are offered as loose petals only — no wreaths, cellophane or anything that does not return to nature.

4

Under association rules

As a member of the Japan Sea Scattering Association, we operate under its guidelines and the 2021 national guidelines of the Ministry of Health, Labour and Welfare — including weather standards, safe vessel operation and environmental testing of the ashes.

What the Ceremony Looks Like

A quiet, non-denominational farewell — flowers, water, and the ship's bell. Religious elements can be arranged on request.

You Do Not Have to Scatter Everything

Scattered ashes cannot be recovered — so many families keep a small part. We prepare this before the ceremony.

All ashes returned to the sea

All to the sea

The complete return — everything is scattered at the ceremony. A clean farewell chosen by those who feel the sea is where their loved one belongs.

A palm-sized mini urn kept at home

Most to the sea, some at home

A palm-sized mini urn — egg-shaped ceramic or glass — that sits on a shelf or in the living room. No home altar needed. Dividing into an urn you bring is ¥5,500 (tax incl.).

Memorial jewellery holding a small amount of ashes

A trace kept close

A quantity about the size of a grain of rice, sealed inside a memorial ring or pendant — carried with you, anywhere in the world. Keepsakes ship internationally.

How to Arrange a Sea Burial

Six steps from first email to certificate. From overseas, everything can be done in English by email.

  1. Free consultation

    Tell us your situation by email or through our English form — "just asking" is welcome. Consultation and quotes are free, and we reply within 2 business days.

  2. Plan and written quote

    We propose the plan that fits your wishes and confirm the total in writing. Nothing is added to the quoted amount afterwards.

  3. The ashes reach us

    Bring them in person, send them within Japan by Japan Post (yu-pack) with our packing guidance, or ask a relative in Japan to do so. Travelling from abroad, we advise on documents and airline rules for your route.

  4. Powdering

    We grind the ashes to a fine powder as the rules require — by hand, with environmental-safety testing (hexavalent chromium check and neutralisation). If you wish to be present for this, ask us.

  5. The ceremony

    Flowers, an offering of water, the ship's bell — attended by you, or performed carefully on your behalf. The ceremony is photographed for you.

  6. Certificate and afterwards

    You receive a certificate with the date and GPS coordinates (English version on request), with photos. Later, a memorial cruise can take you back to the same waters.

Frequently Asked Questions

More questions — including bringing ashes into Japan — are answered on our English top page.

How do you decide the date? What if the weather turns?

Attended ceremonies are booked around your travel dates; unattended ceremonies join the next suitable sailing. Sailings are confirmed about two days ahead based on sea conditions, and if the weather prevents a safe departure, the ceremony is rescheduled at no charge. Safety standards follow the Japan Sea Scattering Association guidelines.

Where exactly are the ashes scattered?

Off Kagoshima, ceremonies take place in Kinko Bay within sight of the volcano Sakurajima; off Fukuoka, in the waters beyond Hakata Bay. Both are designated sea areas away from shores, fishing grounds and sea lanes. The exact position of your ceremony is recorded by GPS and printed on the certificate.

Can the certificate be issued in English?

Yes. The certificate of sea burial — date, sea area and GPS coordinates — can be issued in English on request, at no extra charge. Overseas families often use it as the family's permanent record of the farewell.

Can we watch the ceremony from overseas?

Yes. For unattended ceremonies we can arrange video recording or a live stream (Zoom or similar), so family members anywhere in the world can be present at the moment of the farewell. Ask for this when you request your quote.

Is a grave or family altar still needed afterwards?

No — after a sea burial there is nothing that must be maintained, and no ongoing fees. This is one reason families closing a family grave (hakajimai) choose it. Those who want a focal point for remembrance often keep a mini urn or memorial jewellery, or join our memorial cruise on anniversaries.

Can you also handle closing a family grave in Japan?

Yes. We handle grave closure (hakajimai) across Kyushu — removal of the stone, retrieval of the remains, the paperwork, then powdering and sea burial — as one service. If your family grave is in Japan and you live overseas, we can manage the whole sequence with a relative in Japan or directly with you by email.
