If you are really hoping to get a reservation no matter what, then it might be a good idea to make a request on tableall, although it may end up costing a fairly expensive fee.

Most of the top hotel concierge services in Tokyo can easily book this shop, too. If you are staying at a 5 star hotel and they are telling you they cannot secure a reservation at Takamitsu, I'd recommend moving to a different hotel.

Well, i thought it was a turnoff too, but takamitsu-san's sushi really isn't bad. And his louis vuitton displays has achieved its desired impact - making you remember his restaurant(albeit in a bad way) compared to the other thousands of sushi restaurants which you probably won't even know their name.

If you like plenty of uni, it might be better to visit in summer. Saw on tabelog people having fewer types of uni when people visited during feb/mar period.

While there are few sushi restaurants throughout Tokyo that have various kind of uni available in March, Takamitsu will have at least 4 to 5 varieties of uni ready to serve.
So if you like uni, I think that Takamitsu would be worth a visit, even in March.

Thank you both!

@guest which hotel did help book for u? I tried calling but couldn’t get through at all.

@guest I used park Hotel Tokyo to make the reservation, Park Hotel Tokyo concierge has never failed me unless you are looking for those introduction only sushiyas like saito, sugita etc...

I would say the order is "羽立生うに" (brand) from 羽立水産 (Hadate company), followed by the "生うに" from 東沢水産 (Higashizawa), then the two from 橘水産 (Tachibana), "生うに" and "まるひろの生うに."
Recently the "生うに" from ダイセン水産 (Daisen) has also been popular.
