Can someone please suggest some sushi places in Tokyo (Ginza, Shibuya, Shinjuku, Tokyo Station, Ueno, Roppongi) that are not on the very high end (less than 100,000YEN per person)?
Otaru Masa sushi in Shinjuku
Masa Sushi is a famous sushi place in Otaru, Hokkaido. You can enjoy fresh seafood shipped from Hokkaido :)
Manten Sushi near Tokyo station
I have not been to this place but my friend once recommended me. Lunch is especially affordable.
Here are places I have been and would like to recommend to anyone!
Nemuro Hanamaru (根室花まる)
This is a conveyor belt type sushi restaurant, but don't underestimate the quality. The shop is originally from Hokkaido, where is one of the best seafood resource in Japan. The quality of raw fish here is promised!
Katsu Seibu Shibuya (活 西武渋谷)
This is another conveyor belt sushi restaurant in Shibuya. As the store is part of the famous sushi group Umegaoka Sushi No Midori, they have a good quality of sushi-go-round. The store is always crowded, so be ready to line up.
Another conveyor belt sushi restaurant... (I like conveyor belt sushi!) Numazuko's specialty is their "mega" series. They put lots and lots of fish on rice!
