Okinawa Marine Leisure
White Paper 2026

Record-high visitor arrivals. Record-tying marine leisure accidents.
An annual report on the state of Okinawa's ocean, built on official statistics and field knowledge. (Inaugural edition)

Published by the Association of Marine Leisure Promotion (AMP) | First published July 4, 2026 | 2025 (Reiwa 7) figures include preliminary and provisional data

What Happened in Okinawa's Waters in 2025

In 2025, Okinawa welcomed a record 10.75 million visitors. In the same year, 111 people were involved in marine leisure accidents — tying the highest number since records began in 2001. Tourism at its peak and ocean safety in crisis are advancing side by side.

By activity, snorkeling leads with 19 victims, followed by diving (15) and SUP (13). Accidents are occurring at a pace exceeding 2025 — itself a record-tying year — making countermeasures all the more urgent.

Who Is Getting Hurt — and Doing What

Over the past five years (2021–2025), 469 people were involved in marine leisure accidents, including 129 deaths and missing persons. The data points clearly to where action is needed.

By activity: snorkeling accounts for a third of accidents — and half of all deaths

Snorkeling154 (63 deaths)
Swimming84 (19 deaths)
Scuba diving82 (25 deaths)
SUP42 (3 deaths)
Fishing33 (9 deaths)
Towed water toys25 (6 deaths)

Five-year totals, 11th Regional Coast Guard HQ (469 victims in total, incl. tidepooling 15 and other 34)

Snorkeling is often seen as an easy activity anyone can enjoy. The data tells a different story: it is the deadliest activity in Okinawa's waters. Of 129 deaths and missing persons over five years, 63 — nearly half — occurred while snorkeling.

Three decisive facts

87%
of snorkeling and swimming fatalities were not wearing a life jacket
49%
of accident victims aged 50+ died or went missing (about 1 in 2)
70%
of all deaths and missing persons were aged 50 or older

Each activity has its own risk profile

  • Scuba diving — 93% of victims were tourists. 84% of fatalities were aged 40+.
  • SUP — 69% of victims were local residents; 78% were first-timers or had under one year of experience. Here it is beginners among residents, not tourists, who get into trouble.
  • Snorkeling & swimming — tourists have made up over 70% of victims every year since 2022, with accidents among international visitors remaining high.

The Structural Challenge — 3,384 Registrations, Only 2.5% Certified

Businesses registered under Okinawa's Water Safety Ordinance total 3,384 (2,388 unique operators). Yet only 85 businesses — a mere 2.5% — hold the Public Safety Commission's "Maru-Yu" certification for excellence in safety measures.

Business typeRegisteredMaru-Yu certifiedRate
Pleasure boat operators1,301342.6%
Diving operators1,093302.7%
Snorkeling operators1,008162.5%
Beach operators6951.6%
Marinas900%

This is less a failure of individual operators than of the system itself. Certification brings no market advantage, and going without it carries no penalty — so operators who invest in safety lose out in price competition. That structure has gone unaddressed for three decades. Building a market where travelers can identify safe operators is the next challenge for Okinawa tourism.

AMP Initiatives (2023–2026)

Ocean watch infrastructure (adopted by the Ministry of Internal Affairs and Communications)

A receiving network for "SEAKER" GPS trackers using LPWA (ELTRES) covers the entire Yaeyama region via stations on Ishigaki, Yonaguni and Hateruma, and the entire Kerama waters including Aguni via stations on Kerama and Kumejima. Combined with the existing network around Okinawa Main Island built by Sony, coverage now extends to nearly all prefectural waters. It is a preventive safety infrastructure — designed not to search for the drifting, but to keep drift from happening. Since 2025, an insurance-backed plan with Sompo Japan has also been available.

Safety standards, training and data (Nippon Foundation grant program)

AMP has produced crisis-management manuals and over 30 safety training videos for diving, kayaking, snorkeling and more, built a database that centrally manages training attendance, and deployed emergency medical oxygen kits at 71 stations across the prefecture, operated together with renewal-based certification training. A further 100 stations are being added in fiscal 2026 toward a prefecture-wide medical oxygen network.

Coral reef conservation and orderly use of the sea (Okinawa Sustainable Tourism program)

Coral conservation was long discussed but rarely acted upon, as competing interests stalled progress. On Ishigaki Island, AMP convened a mooring buoy council bringing together fisheries cooperatives, marine operators, government and experts — creating, for the first time, a forum where stakeholders speak beyond their positions. The council is turning anchoring damage prevention and safe use of the sea into concrete local practice. In Yaeyama, operators have also begun forming their own council for safety and conservation.

Research and policy advocacy

Joint research with Meio University is developing the "Okinawa Glocal Safety Standard," integrating international standards with domestic law. Through expert testimony to the Prefectural Assembly and study sessions with assembly leagues, AMP brings field realities into policy.

Five Recommendations — Making Okinawa the World's Safest Place to Learn the Ocean

  1. Make life jackets part of Okinawa's ocean culture87% of snorkeling and swimming fatalities were not wearing one. We call for operators, hotels and government to jointly build an environment where wearing one is the norm.
  2. Teach snorkeling as an ocean survival skillWith half of all deaths occurring while snorkeling, this is a matter of education. We propose an all-weather ocean safety education hub, aligned with the nationwide consolidation of school pools.
  3. Build a market that rewards operators who invest in safetyFacing a 2.5% certification rate head-on, we call for real incentives for certification and a review of the registration-only system.
  4. Manage the sea by "using and protecting" — mooring buoys and conservation feesWe propose installing and codifying reef-safe mooring buoys and a conservation fee that lets visitors take part in protection.
  5. Shift to data-driven safety governanceWe call for integrating data now scattered across agencies and operators, and for continuing this white paper as an annual fixed-point observation.

Sources, Evidence Status and Update History

This white paper is a public reference page. Figures are organized by source type so that readers can distinguish official statistics, preliminary figures, public reporting, and analytical interpretation.

Evidence status

Category How it is used in this page
Confirmed official source Used for visitor arrivals, police and coast guard statistics, public safety ordinance references, registered operator lists, and Maru-Yu safety certification references where an official public URL is available.
Preliminary or provisional figures Used only where the source itself indicates preliminary, provisional, flash, or as-of-date status. These figures should be rechecked when final annual statistics are published.
Public news reporting Used only as a temporary reference for flash figures when an official public release URL has not yet been confirmed. It is not treated as a final official statistic.
Analytical interpretation Policy implications and recommendations are editorial analysis based on the cited public sources. They do not replace official guidance, legal interpretation, rescue procedures, medical judgment, or safety training.
