Fresh Hokkaido (Nemuro) seafood nigiri at reasonable prices
Nemuro Hanamaru is a Hokkaido-born kaiten-zushi (conveyor-belt sushi) chain that ships its fish overnight from the port town of Nemuro, and its fifth-floor outpost inside KITTE Marunouchi -- just steps from Tokyo Station's Marunouchi South exit -- is one of the busiest lunch counters in the neighborhood.
The draw is simple: fish this fresh rarely comes at these prices. Standouts on the belt include hon-maguro (bluefin tuna, sometimes featured in rare-cut promotions), rich sea urchin, and salmon lightly torched aburi-style or cured in white soy sauce -- and portions run noticeably larger than at a typical sushi-ya, with visibly thicker cuts and toppings piled high rather than the thin, standard-size pieces found elsewhere. The dining room doesn't try to be quiet or precious; it's bright, efficient, and loud with the clatter of plates, which suits its role as a reliable, no-fuss stop for office workers and travelers passing through the station.
That popularity comes with a catch: there's no reservation line, only a ticket-dispensing waitlist system, and waits of an hour or more are common through lunch and dinner peaks -- arriving right at opening or in the mid-afternoon lull is the easiest way around it. Once seated, an English menu is available on request, so picking plates straight off the belt or filling in a numbered order sheet needs no Japanese -- there's no touchscreen ordering here, just paper slips and the chefs behind the counter. Credit cards and IC transit cards are accepted, so there's no need to carry cash.
For pescatarian diners, this is an easy yes -- the menu is built around raw and cooked seafood rather than meat. It's not a fit for gluten-free diners, since soy sauce and several prepared items rely on wheat-based seasoning, and shared prep surfaces mean cross-contact with allergens is likely on a fast-moving conveyor line.

★ 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.

★ Gluten-free shio (salt) ramen with rice-based noodles; veggie 'Vegisoba'
A popular Tokyo Ramen Street shop offering a gluten-free salt ramen made with rice-based noodles, plus its colorful vegetable 'Vegisoba'. It is a has-options shop, not a dedicated GF kitchen — the official site warns of possible cross-contamination, so it is not celiac-safe.
