There is a brand new place to have breakfast at Tsukiji Market that is void of tourists and offering a value priced meal. There is a new facility, Tsukiji Uogashi, with about sixty retail shops for seafood and produce on the first floor. The first floor is open to the general public after 9 a.m. Prior to that it is for trade people only. The second floor is administrative offices and is off limits to visitors.
The third floor is a new shokudō (dining hall) that is run by a non-profit organization to supporting Japanese seafood and produce from Tsukiji Market. The recommended breakfast, only 650 JPY, included a small grilled fish filet, simmered fish with daikon, miso soup, pickles, and rice. The breakfast above was only 800 JPY and was a large serving of yellowtail and daikon simmered until tender in a sweet soy broth.
The dining hall on a recent morning was very quiet, only a handful of customers. The dining hall is so new that many don’t know about it yet. I was seated at a counter overlooking the open kitchen. The staff were very friendly and genki (enthusiastic).
The shokudō is open from 7 a.m. to 2 p.m. Lunch prices too are reasonable, with a sashimi donburi for only 1,000 JPY or a sashimi set lunch for 1,200 JPY. I highly recommend starting your morning here if you will be visiting Tsukiji Market.
