Located on the third floor of the Otsu Municipal Wholesale Market, Kaisendon Maguroya is a popular seafood bowl restaurant that uses fresh seafood carefully selected by the owner, who is a seafood wholesaler. Located inside the market, the lively atmosphere is also one of its attractions.

The signature dish is the "Raw Bluefin Tuna Bowl" made with high-quality domestic bluefin tuna. A wide variety of menu items can be enjoyed at reasonable prices, including a luxurious bowl that allows you to taste lean, medium fatty, and fatty tuna all at once, and a "Seafood Bowl" that includes several types of seasonal seafood purchased that day.

The freshness and prices that can only be found at the market are the restaurant's greatest strengths, and it is not uncommon for a line to form as soon as the restaurant opens. It is recommended for those who want to enjoy fresh and delicious seafood at a good price.
