Sushi Sei is a popular sushi shop at Tsukiji Market that has a branch inside of Tokyo Station. There is often a line of salarymen outside of the shop before it opens at 7 a.m. The breakfast options include sashimi or donburi (sashimi over a large bowl of rice). There are also two versions of ochazuke. Ochazuke is a bowl of rice with toppings such as seafood or pickles that is then drenched with tea or a mix of dashi and tea. Sushi Sei has sea bream in a creamy sesame dressing or salmon belly with ikura. Above is the salmon and ikura set as it is presented.
The diner assembles the toppings to the rice and then pours the savory tea broth over the bowl. This breakfast is only 670 JPY. At current exchange rates I think it is about $5 USD. It is garnished with mizuna greens and arare, colorful rice crackers.
There are seats at the sushi counter, but this early in the morning the counter is not filled with seafood yet. It was busy recently on a weekday morning, and I was happy to see that most of the customers were ordering the ochazuke. It is a popular comfort food dish. I usually drink it as a last dish at an izakaya after a night out of drinking, but it is also an excellent way to start the day.
Sushi Sei first opened 120 years ago, in the original fish market, before it moved to Tsukiji.
