Slippery Business: Tokyo Unagi Review of Nodaya and Uomasa

Unagi (freshwater eel), the ultimate Japanese comfort food that somehow costs more than a designer handbag. If you’re going for a "proper" experience in Tokyo, be prepared for two things: a hole in your wallet and a choice between "Farmed" or "Wild" eel. Wild ones are the elite athletes of the river world and come with a much heftier price tag. I hit up two spots to see if the hype—and the bill—are justified.

1. The Charcoal Master: うなぎ魚政 (Unagi Uomasa)

Located a bit of a trek away in Katsushika, Uomasa is for the serious unagi pilgrims. This isn't "fast food"—each eel is kept alive until you order it, then killed, skewered, and grilled over top-tier Kishu Binchotan charcoal.

Grill fish bone and liver

Unagi Uomasa is often talked about in hushed, reverent tones, and while it’s undoubtedly a top-tier bowl, the reality is a bit more grounded than the poetry online suggests. The hook here is the absolute freshness; they keep the eels swimming until you order. The texture is undeniably soft and rich—far superior to any supermarket version—carrying a decent hit of charcoal smoke from the Binchotan grill. They specialise in "Bando Taro" brand eel, which is essentially high-end farmed eel designed to taste wild, and it does have a clean, sweet finish. However, the secret sauce, while balanced, didn't exactly blow my mind given the hefty price tag and the long trek out to Katsushika. It’s a technically perfect meal, but unless you’re an unagi fanatic, you might find the "divine" descriptions a bit of a stretch.

Great flavour and nicely grilled

2. The Historical Heavyweight: 入谷鬼子母神門前 のだや (Nodaya)

If you want the history without the long-distance travel, Nodaya in Iriya is a stone's throw from Ueno. They’ve been at this since 1868 and use a legendary "Manben Kaeshi" technique, which involves turning the eel thousands of times over the fire.

I personally prefer Uomasa as it as stronger flavour

Nodaya feels more accessible in every way. It’s easier to snag a booking, closer to the city center, and generally a bit kinder to your budget. The quality is remarkably high, though the seasoning (the tare sauce) felt a bit lighter and less punchy than Uomasa’s. It’s a cleaner, more refined taste, which might suit those who want to taste the "eel" rather than the "smoke." Unless you’re a professional eel critic, this is likely the better choice for a holiday meal.
