Just Before the Day of the Ox, Eel Fever Accelerates Further! "Devil's Feast," Weighing Over 1kg and Featured on TV, Extended to End of July Due to Popular Demand

Nadayu Unato is pleased to announce that the "Devil's Feast" (Unagi and Dashimaki Tamago Donburi, Akuma Mori), a power menu item weighing over 1kg, and other large-portion menus, originally part of the "Baku-mori Eel Festival" special campaign celebrating our 25th anniversary, will have their sales period extended to July 31, 2026 (Fri) due to overwhelming popularity.

Extended to the end of July due to popular demand! Further igniting the eel season just before the Day of the Ox.

The "Devil's Feast" is an exceptionally voluminous menu item befitting our 25th anniversary, featuring a whole grilled eel and a whole Unato-made dashimaki tamago, generously piled on top. It weighs over 1kg. This dish offers a visually and gastronomically impactful experience, with grilled eel overflowing from the bowl, complemented by fluffy dashimaki tamago.

It's a truly "devilish" voluminous menu where you can simultaneously enjoy the robust flavor of eel grilled to a fragrant crisp over charcoal and the gentle umami of dashimaki tamago.

"Unagi and Dashimaki Tamago Donburi, Devil's Feast" ¥2,980 (tax included)

Since its launch, its overwhelming appearance and satisfying portion have become a hot topic. We've received numerous reactions, including posts of completion and challenge reports on social media, and features on multiple TV programs.

Although initially scheduled to end sales on June 30, 2026 (Tue), we have decided to extend the sales period to July 31, 2026 (Fri) in response to requests from customers who wish to "still try it."

With the Day of the Ox approaching, attention on eels is intensifying. We aim to further liven up the eel season with this hearty dish unique to Nadayu Unato.
