Over the past 10 years, the price of fish has been steadily increasing. Recently, on TV, it was mentioned that the prices of the top 3 popular fish - salmon, tuna, and yellowtail - have increased by around 100 yen per 100 grams (about 30%) over the past 10 years. This increase in prices is mainly due to factors such as the scarcity of resources and changes in fishing yields. In Japan, there has been a trend of moving away from rice and fish in diets, but the issue of fish resources is also significant, especially with the high demand for popular fish species affecting price formation. In the midst of this, businesses focusing on utilizing the large amount of unused fish that is being discarded (some estimates say up to 30% of fishing yields) have been gaining attention in recent years, with ventures such as subscription services and online sales starting to emerge.
Thinking about all this, I suddenly felt like eating fish one day and after exploring a new restaurant near my workplace, I came across this place located in a back alley in Ogawamachi, Kanda (address: Kanda Tsukasamachi 2-chome). The owner of this restaurant, Akio Numano, hails from Shizuoka's Yaizu, which boasts the highest fish haul in Japan. After graduating from university, Numano jumped into the food and beverage industry, but as his desire for independence grew, he began to consider returning to his hometown to start his own business. However, as he pondered various ideas, he felt a strong urge to offer affordable Yaizu tuna to the people of Tokyo, leading him to open a tuna izakaya in Kanda Ogawamachi 1-chome in 2008 (formerly Xibi). The name "Xibi" means "tuna" in Portuguese, so it's quite straightforward. Later, due to the demolition of the building, the shop was forced to relocate, and in December 2019, it reopened in a new location nearby, retaining the same name from the previous shop.
The new location of the shop is just off Hongo Street, a short distance from "Ministop Kanda Mitodomachi Store," on the right after turning left at the intersection about 100 meters towards Sotobori Street. There is a popular tsukemen restaurant, "Tsukemen Kinryu," nearby. Recently, my workplace had a somewhat relaxed atmosphere after a major event, but such peaceful times never seem to last long. On this day, I had a busy morning with multiple consultations, so I ended up having lunch a bit late and visited this restaurant around 12:30. Although it was the peak lunch hour, the restaurant was surprisingly lively, with about 80% of the seats occupied. The interior of the restaurant has a kitchen on the right side with a counter seating for 6, and table seating for 16 on the left side. I was seated at the available counter seat. The shop is run by the owner, Mr. Numano, and a woman who appears to be his wife. There is a small lunch menu with photos on the table, which is very simple, consisting of only 5 types of rice bowls (all related to tuna) priced from 850 yen to 1,200 yen, which is reasonable for lunch. However, as a tuna specialty store, there are no premium cuts like chutoro, and the main menu consists of akami, bincho, and yukke. At that time, I didn't quite understand the menu strategy. I ordered the top menu item, the Sibi Don for 950 yen. The Sibi Don is a marinated rice bowl with tuna akami and bincho. It took quite a while to prepare, and after waiting for about 11 minutes, my Sibi Don was finally served. The Sibi Don consisted of 6 slices of tuna akami and bincho.
