There's a snobbery about conveyor belt sushi that I held onto for longer than I should have. Then I actually ate at a good one in Tokyo and quietly dropped it.

The assumption is that kaiten sushi — the restaurants where plates circle on a belt and you grab what you want — is the fast food version of sushi. Budget option. Tourist trap. What you eat when you can't get a reservation anywhere proper. That's wrong, and if you've been to Japan recently you'll know it's wrong.

What Kaiten Sushi Actually Is

The top kaiten sushi chains in Japan — Sushiro, Kura Sushi, Hamazushi, Heiroku — operate at a quality level that would make most Western sushi restaurants look embarrassed. The fish is fresh, the rice is properly seasoned, the cuts are generous, and the whole operation runs with a precision that only Japan could produce.

At a good kaiten place, the belt isn't just for browsing — it's a conveyor of exactly what you want, moving past you at a pace that's been optimised over decades. You can also order directly via tablet and have specific plates delivered to you on a dedicated lane. The system is genuinely impressive.

What We Ordered

We started with maguro — bluefin tuna — which arrived two pieces to a plate on a ceramic dish with a gold-painted rim. The fish was deep red, properly cold, and had the kind of clean, fatty flavour that makes you understand why tuna is the reference point for sushi quality. We ordered four plates of it between us.

After that: salmon belly, which was obscenely good; scallop with a tiny dot of yuzu; uni (sea urchin) which is always a gamble and landed well; and a plate of tamago (egg) at the end because Johnny always orders tamago at the end and I've stopped questioning it.

The Value

We spent about 3,500 yen each, including two beers apiece. That's roughly £18. For the quality and the volume of what we ate, that figure is almost offensive. A comparable omakase experience in London would be four or five times that, and the fish wouldn't be as fresh.

This is the thing about Japan's food culture that consistently catches you off guard: the baseline is just higher. A chain sushi restaurant isn't coasting on its brand. The competition is too fierce and the customer expectations are too demanding. They have to be good or people simply don't come back.

Tips

Go for lunch if you can — the turnover is high, which means the fish is fresh, and it's usually quieter than the dinner rush. Use the tablet to order the things you specifically want rather than waiting for them to come around. And don't skip the miso soup — at a good kaiten place it's made properly and it's usually included.

Don't skip the kaiten places. Sushiro and Kura Sushi are everywhere. Go for lunch, order the tuna first, use the tablet, and get a beer. You'll spend less than you expect and eat better than you thought possible.
