Nakau in Minato Offers Free Samples of Premium Southern Bluefin Tuna Tekka Don

Nakau, a popular donburi and Kyoto-style udon chain in Minato, Tokyo, is launching its new Southern Bluefin Tuna Tekka Don starting July 22, 2026, at 11:00 AM. To celebrate, selected locations will offer free samples of this premium seafood bowl.

This special tuna donburi features generous portions of chutoro (medium fatty tuna) and akami (lean tuna) from Southern Bluefin tuna, delivering a rich and satisfying flavor. The offer is expected to be popular, especially on weekends, so timing your visit is recommended.

About Nakau’s Southern Bluefin Tuna Tekka Don

The Southern Bluefin Tuna Tekka Don is a seafood bowl piled high with both the melt-in-your-mouth chutoro and flavorful akami cuts. It highlights the refined taste and delicate sweetness of carefully selected Southern Bluefin tuna. Alongside this, Nakau also offers a “Yamakake” version topped with fluffy grated yam, which adds a refreshing smoothness to the dish.

For those with a bigger appetite, Nakau provides a “Tokumori” (extra-large) serving that doubles the tuna amount compared to the regular bowl, served over a large portion of rice. This makes for a hearty and indulgent meal perfect for tuna lovers.
