Project Background: Why Eels are the "Best Sauna Meal
With the recent sauna boom, "sauna rice," a post-sauna meal, is attracting increasing attention. Yamada Suisan has conducted research on the "ideal post-sauna meal" from a nutritional perspective, and confirmed that eels satisfy the requirements.
Yamada Suisan has confirmed that eels meet these requirements.
1. high quality protein: It is important to actively consume protein, which is a material for muscles, after sauna.
2. effective nutrients for recovery from fatigue: Nutrients that support energy metabolism and help recovery from fatigue must be replenished
3. warm foods to prevent cold: Avoid cold foods, and use warm foods to prevent body cooling and relaxing effects
3 reasons why eels satisfy all the requirements.
1. rich in high-quality protein: Approximately 100g of eel contains about 20g of protein. Animal protein is the best material for muscle
2. overwhelming amount of vitamin B1, the king of fatigue recovery: Each 100g contains 0.75mg of vitamin B1 (about 7 times more than spinach). Since it is an important nutrient that converts carbohydrates into energy, the effect of recovery from fatigue is maximized with eel rice bowls.
3. filling the post-sauna body with a warm meal: the high-quality fat in the eel is slowly absorbed by the body, providing lasting satisfaction
■King of Athletes Keisuke Ugishiro is appointed as the image character
Keisuke Ujiro, the Japanese decathlon record holder and King of Athletes, has been appointed as the image character for this project.
Keisuke Ujiro himself is a "sauner" who actively takes a sauna when he rests, and enjoys "Yamada's Eel" on a daily basis to recover from fatigue and maintain his condition.
Keisuke Ujiro comments:
As an athlete, rest and nutritional management, in addition to training, are essential in order to achieve peak performance. Eels after sauna are an ideal meal to efficiently consume the nutrients necessary to recover from fatigue. Through the "Sauna Meal Project," we hope many people will experience the wonderful combination of sauna and eel."
The first phase of the "Sauna Rice Project": Started on November 1 at "Marcin Spa" in Sasazuka, Kanagawa Prefecture
As the first step of the "Sauna Rice Project," "Yamada's Eel" menu will be offered at the popular sauna facility "Marcin Spa" in Sasazuka, Tokyo, from November 1, 2025.
Features of Yamada's Eel
Healthy eels are delicious.
Yamada's Eel" is a "drug-free eel" that is raised to be "healthy" without using any drugs such as antibiotics and synthetic antibacterial agents. In Shibushi City, Kagoshima Prefecture, where groundwater is abundant, professional eel farmers, "eel masters," who eat and sleep with eels 24 hours a day, 365 days a year, carefully raise eels one by one under the motto, "Be gentle to eels. Because they are healthy, there is no need to add extra ingredients or fat to their feed or force them to fatten up. The eels grow up to have delicious fat and firm flesh, as they should.
Our special production method
The eel is carefully grilled four times with sauce and grilled over charcoal to reproduce the craftsmanship of a specialty restaurant. The sauce is based on soy sauce aged in wooden barrels to bring out the best flavor of the eel.
The range-up gives it an authentic taste.
Easiness of cooking is another great feature of "Yamada's Eel". Just by heating it up in the microwave, you can enjoy the authentic taste of eel.
Yamada's Unaju" is a frozen product that realizes operational efficiency.
The frozen product "Yamada's Unaju" is an authentic eel dish combining Yamada's eel and "Yumeshizuku" rice produced in Karatsu City, Saga Prefecture. The product can be easily prepared in a microwave oven, eliminating the need for cooking rice and sauce application processes, making it possible to offer authentic unaju while improving operational efficiency.
■ Provision of Promotional Materials
The project will provide promotional materials such as original B2 size posters (2 types) featuring Keisuke Ujiro and original "Sauna Rice Stickers" to increase awareness at sauna facilities.
Future Development
Through the "Sauna Rice Project," Yamada Suisan aims to offer "Yamada's Eel" at sauna facilities nationwide. Through the development of sauna culture and the creation of new value for eel, a traditional Japanese food, Yamada Suisan will support people's healthy lifestyles.
