You've Had Eel at a Japanese Restaurant. This Is What It's Supposed to Taste Like at Home.

Most eel sold in the U.S. is farmed overseas, frozen, and finished with a generic sauce that has very little to do with authentic Japanese kabayaki. If that's all you've tried, you haven't really had unagi. Here's what makes the difference — and how to experience the real thing without booking a flight to Tokyo.

 

What is kabayaki, exactly?

Kabayaki (蒲焼き) is the traditional Japanese method of preparing eel. The fish is split open, skewered, grilled over high heat, and repeatedly lacquered with a house-made tare sauce — a blend of soy, mirin, sake, and sugar — until the surface caramelizes into a deep, glossy coat.

The result is something genuinely unlike anything else: tender, almost buttery flesh under a savory-sweet glaze with a faint smokiness underneath. It has been Japan's most celebrated comfort food for over 400 years, the dish Japanese people reach for on their most important occasions — not because it's exotic, but because it's deeply, consistently satisfying.

Served over steamed rice, it becomes unadon or unaju — Japan's answer to the ultimate rice bowl. Simple. Rich. Unforgettable.

"Kabayaki is not a condiment or a topping. It is the dish. The tare, the technique, the quality of the eel — every element is load-bearing. There is no room to cut corners."


Why does most eel in the U.S. taste disappointing?

The eel category in the American market has a quality problem. The majority of products are made from eel farmed outside Japan, processed at scale, and coated with a teriyaki-adjacent sauce designed to appeal broadly rather than authentically. The texture is often mushy. The flavor is flat.

Authentic kabayaki depends on three things most mass-market products skip: the quality of the eel itself, a properly developed in-house tare, and a craftsman willing to taste-verify every batch before it ships. Remove any one of those, and you have a product that looks like kabayaki and isn't.

Typical U.S. market eel Unagiya-Kawasui kabayaki
Farmed outside Japan, origin often unclear Sourced exclusively from licensed aquaculture farms in Western Japan
Generic teriyaki-style sauce Proprietary in-house tare, developed over years of restaurant supply
Machine quality checks only Taste-verified by craftsmen whenever new eel is received
Fixed single-origin sourcing year-round Seasonally adjusted sourcing from carefully selected farms in Japan


A note on sourcing: what our sourcing means

We source exclusively from Japan — full stop. While our eel is sourced primarily from Western Japan, we do not limit ourselves to one area alone. Instead, we carefully select from licensed aquaculture farms across Japan based on seasonal conditions and overall quality.

This approach allows us to choose the best eel available at any given time, rather than relying on a fixed region year-round. It takes more work, but it's how we maintain the consistent quality and taste we aim to deliver.

How to make a proper unagi rice bowl at home

You don't need special equipment. You need rice, heat, and about three minutes.

  1. Cook Japanese short-grain rice (look for "sushi rice" at any grocery store — it's the same thing). Scoop a generous portion into a bowl.
  2. Heat the kabayaki in a toaster oven at 350°F for about 60 seconds. This re-crisps the surface and gets closest to the original grilled texture. A microwave for 30–40 seconds also works if you're in a hurry.
  3. Lay the eel over the rice and drizzle with the included tare sauce.
  4. Finish with sansho pepper if you have it — it's a Japanese mountain pepper with a citrusy, slightly numbing heat that cuts through the richness beautifully. Find it at Asian grocery stores or on Amazon. If you don't have it, a few drops of yuzu juice or even a light squeeze of lemon works as a substitute.


Frequently asked questions

What does kabayaki actually taste like?

Rich, savory, and slightly sweet — with a smoky depth from the grilling and a glossy, caramelized glaze from the tare. The texture is tender and almost buttery, not fishy. If you've had unagi at a good Japanese restaurant, this is that flavor. If you haven't, think of it as the most satisfying rice bowl you've never tried.

I've never eaten eel before. Is this a good place to start?

Yes. Kabayaki is one of the more approachable ways to try eel for the first time — the tare glaze is familiar and deeply savory, and the texture is far less intimidating than raw preparations. Most first-timers are surprised by how much they enjoy it.

Why is it shelf-stable? Does it contain preservatives?

The product is sealed using a retort packaging process — a heat-sterilization method widely used in Japan for premium prepared foods. It preserves flavor and safety without relying on artificial preservatives. No freezer needed, and the flavor is not compromised.

Is the eel actually from Japan?

Yes. We source exclusively from licensed aquaculture farms in Japan, primarily in Western Japan. We adjust our sourcing seasonally based on which regions are producing the best-quality eel at that time.

What rice should I use?

Japanese short-grain rice gives the best result — it's sticky enough to hold together under the eel and absorbs the tare well. Look for it labeled "sushi rice" at most grocery stores, or at any Asian market. Long-grain rice works in a pinch, though the texture will be different.

Is $49.99 for one serving really worth it?

That depends on what you're comparing it to. A comparable unagi don at a quality Japanese restaurant in the U.S. runs $35–$60 — and you're driving there, waiting, and tipping. This is the same category of product, made with the same standard of sourcing and preparation, heated in your kitchen in under two minutes. For a weeknight that deserves something better than takeout, we think the math works.
