Kashima, a city in southwest Saga, was known for very little when the prefecture was founded. With no highway or shinkansen line connecting it to the rest of Japan, Kashima had to make itself known if it wanted to attract visitors. In order to do this, the mayor decided that they would hold a sporting event in Kashima that would attract tourists from all around the area, but it would not be on the dry land, but on the mudflats at the edge of the city, and so the Gatalympics was born.
Often called the craziest sporting event in all of Japan, at around the end of May every year tens of thousands of tourists and locals alike make their way down to Kashima in order to compete. Normal sporting events such as the 25m dash or a cycling race are made all the crazier by mountains of mud. Twenty-five meters may seem like a short distance but it’s difficult to manage when you are waist-deep in mud. The cycling race is also complicated by lack of brakes and the ever-looming possibility of being thrown off into the mud.
The Kashima Gatalympics is an event held in the mudflats of the Ariake Sea off Kashima city in Saga Prefecture, Japan. The Ariake Sea has a tidal range of six metres, which on a low tide, exposes the vast mudflats on which the games take place. It has become a well known event throughout Saga Prefecture with around 300 athletes participating each year in its early editions, now growing to as many as 2,000 athletes and twelve events, attracting around 35,000 spectators, more than the whole population of Kashima, plus television audiences nationwide.
Do you know? Planning events, festivals, concerts, and cultural experiences in Japan can be overwhelming. Japan Travelo brings everything together in one place, helping you manage your itinerary, transport, and accommodation with ease—so you can enjoy Japan without the stress of planning.
The spirit of the Gatalympics is all about throwing away inhibitions, having fun, and not worrying about making a fool of yourself. Virtually every contestant ends up plastered in mud from head to toe. Even if they manage to keep faces clean, someone is usually kind enough to smear a bit of mud afterwards. The event is also featured in popular culture, including the anime Zombie Land Saga, bringing wide popularity.
The origins of Kashima Gatalympics lie not in ancient agriculture but in modern civic survival. When the prefecture plan for Saga was published in 1984, it was decided that Kashima City would not have a highway or a Shinkansen connection. Mr. Masahiko Kuwahara, the mayor of Kashima, was also the president of the junior chamber. He created a committee called Forum Kashima to improve the city’s cultural calendar.
As a result, the first Kashima Gatalympic event was held on 3 May 1985. Initially, the name proposed was The big athletic meet on the mudflats. Later, a second name The Gata-olympic big athletic meet on the mudflats was suggested. This was eventually shortened to just Gatalympics. The term Gatalympics comes from the name of mudflats in Japanese, Kashima Higata and the Olympics.
As the Gatalympics became well known, the mudflats that had been previously neglected were improved. As a result, the mudflats became an important and valued symbol for the growth of the city as a whole. What was once seen as wasteland became a stage for community pride. The mudflats themselves are ecologically significant, supporting mudskipper fish known locally as mutsugoro, and the event has helped raise awareness of tidal flat conservation.
The event reflects a distinctly Japanese approach to regional revitalization known as machi okoshi, where humor and self-deprecation are used to draw attention to rural areas. Kashima turned its perceived disadvantage, isolation and vast sticky mud, into its greatest asset.
Although not a centuries-old religious festival, the Gatalympics has developed its own beloved customs over four decades.
Opening Ceremony on the Mud: The opening ceremony commences at 10am, with events from 11am to 3pm in traditional scheduling. Participants line up in team uniforms, already aware they will not stay clean. A declaration of fun is made, and safety instructions are given for playing in tidal mud.
Human Mudskipper – Ningen Mutsugoro: One of the signature events is ningen mutsugoro, human mudskipper, a type of fish. Contestants compete on mud sledges, lying flat on boards and paddling through mud with hands, mimicking the local mudskipper fish that hops across the Ariake mudflats.
Mud Sumo – Gata Sumo: Ten women stand on a Styrofoam float, and the last one to remain on the float is the winner. After a few seconds of merciless pushing and shoving, nine women end up in the mud and one emerges victorious. There is also men’s mud sumo, where competitors wrestle while sinking.
Gatachari – Tidal Flat Bike: Contestants ride bicycles on boards laid over mud. To make things more fun, the bikes have no brakes, and plenty of contestants end up coming off the boards and landing in the mud. The cycling race is complicated by lack of brakes and the ever-looming possibility of being thrown off.
Tug of War and Ball Hunt: Other events include tugs of war where teams inevitably collapse into mud, and for kids, a find the balls hidden in the mud game which is absolutely guaranteed to result in an all-over mud bath.
Closing Mud Bath: After events, everyone is invited into the mud for a relaxing dip and to feel the cleansing benefits of the mud. Floating in mud is something everyone should experience at least once. Fire hoses are on hand to help everyone get cleaned up at the end.
Expect joyful chaos, full-body mud coverage, and non-stop laughter. The mudflats stretch for hundreds of meters, grey-brown, sticky, and glistening under sun. Races just starting show clean participants, but there is no way they will be this clean by the time they reach the finish line.
Events include the 25 metre dash, not as easy as it sounds as you sink waist-deep into the mud with every stride, and a bicycle race along wooden planks placed on the mud. Other events include tugs of war and races in which surfboards are paddled through the mud. The obstacle course is a highlight; not many contestants make it through without falling in the mud at some point.
You will see girls covered in mud who do not seem to mind being caked, men and women covered in mud making faces, and swimmers who go for a swim afterwards if they did not get muddy enough during competitions. Spectators line the edge of the mudflats, cheering, photographing, and occasionally getting splashed.
For those who do not wish to get dirty, you can go as a spectator and watch all the shenanigans unfold. Even as a spectator, wear clothes you do not mind getting dirty and rubber boots. Food stalls are set up at Roadside Station Kashima offering local delicacies.

Description: Japan’s craziest sporting event held on the mudflats of Kashima. Often called the craziest sporting event in all of Japan, tens of thousands of tourists and locals alike make their way down to Kashima in order to compete.
Yes, safety is a priority and organizers have decades of experience managing events on the tidal flats, with medical staff and volunteers stationed around the arena. The Ariake mud is soft and fine-grained without sharp rocks, and the tidal range is monitored to ensure competitions occur at low tide when water depth is minimal. While falling is inevitable, injuries are rare beyond minor scrapes, and fire hoses and showers are available immediately after for thorough cleaning.
International tourists are warmly welcomed to participate as athletes, with many teams including visitors from abroad and some English guidance available at Roadside Station. Teams must sign up a few months in advance and adhere to substitution rules where a boy can only be substituted with a boy and a girl with a girl to maintain event categories. Even if you miss team registration, you can join the free mud bath after official events or participate in children's activities and spectator games along the banks.
You should wear clothes you are prepared to throw away or that can withstand heavy mud, such as old T-shirts, shorts, and tight-fitting clothes that will not get pulled off in deep mud. Bring a complete change of clothes, towels, plastic bags for muddy items, sunscreen, and waterproof camera protection, as spectators near the edge also get splashed. Organizers provide all specialized equipment like surfboards, mud sledges, and brakeless bicycles, so you do not need to bring sporting gear.
Spectators on the raised banks generally stay relatively clean, though front-row viewers may receive minor splashes during close races like tug of war and sumo. Roadside Station Kashima has elevated viewing decks and indoor areas where you can watch comfortably without any mud contact, and the event is also broadcast on local television. If you want to stay completely clean, bring a rain poncho and rubber boots and position yourself slightly back from the immediate edge of the competition zone.
Kashima offers cultural sites that complement the muddy fun, including Yutoku Inari Shrine with its stunning hillside torii gates and Hizen Hamashuku sake brewing district with Edo-period architecture. You can visit Oouo Shrine's floating torii that appears at high tide, enjoy Ariake Sea seafood like nori and mudskipper dishes, and relax in nearby Ureshino Onsen hot springs famous for skin-beautifying waters. Roadside Station Kashima itself is a destination for local crafts and panoramic views of the six-metre tidal range that makes the Gatalympics possible.
