★ Edomae nigiri course — soy sauce to fish, all halal-certified
Japan's first halal-certified sushi house, steps from Senso-ji, serving full Edomae nigiri — soy, fish and pickles all halal — with a second-floor prayer room built with the local mosque.
★ Kakinoha-zushi — cured mackerel and salmon pressed onto vinegared rice and wrapped in a persimmon leaf
The Naramachi dining branch of Hiraso, a kakinoha-zushi house founded in Yoshino in 1861, where Nara's landlocked specialty — mackerel or salmon cured and pressed onto vinegared rice, then wrapped in a fragrant persimmon leaf — is served as a sit-down meal a short walk from Sarusawa Pond. Because the toppings are fish, it suits pescatarians but not vegetarians or vegans; the rice is seasoned with vinegar and ordinary soy accompanies it, so it is not gluten-free. Closed Mondays.
★ Plant-based nigiri and sushi sets using vegetable alternatives to fish
A sit-down plant-based sushi restaurant in Shoto (near Shibuya) where every piece is made without seafood or animal products, so there is no fish dashi to worry about. It is not gluten-free (soy sauce and some components contain wheat); reservations are recommended and the venue opened its permanent location in late 2025.
★ Premium nigiri like otoro and jumbo sweet shrimp at modest prices
A popular conveyor-belt sushi restaurant on the 8th floor of Seibu Shibuya, praised for generous cuts of quality fish at modest prices; lines are common. Seafood-forward and good for solo diners, but not gluten-free.
A famous Toyosu Market sushi counter (relocated from old Tsukiji) serving a chef's-selection omakase noted for its premium tuna. Pure seafood-and-rice sushi makes it naturally pescatarian; early market hours and not gluten-free (soy sauce contains wheat).
