Magurobito Okachimachi

Located just a few steps from Okachimachi Station, this standing-only sushi shop carries over 50 varieties of fish, freshly delivered from all over Japan. Hand-moulded nigiri go for as low as ¥80, while their signature fatty tuna (otoro) will set you back ¥300. Weekday lunch sets are also a nice option – ¥1,000 for a set of ten nigiri, a roll and miso soup.
