It's my first time visiting seafood market, impressive! Have been to Tokyo many times but never have chance to go any kind of these interesting places, where requires early morning visit. For this one, very "customer-friendly" as it's basically a wet market with restaurants on upper floor and around to do cooking of what you purchased.
It's not large but offering wide range of selection, everything looks great and I have only one stomach, haha

Merchants are very friendly, no hard selling and I met one lady whom is originally from FuJian, China, working there to serve Chinese speaking tourists. All stores are more or less the same, so, pcik this one with a Chinese lady, easier to communicate

Bought a combo of sashimi, a pack of uni (limited supply during this season), Lobster (sashimi and use the head to make lobster soup), 珍珠贝 (kind of shell). They have a partner restaurant nearby, and I ordered Orion (local beer) and fried vegetables...Everything is Perfect!
