Getting thereJR Kobuchizawa (Chuo Line), about three minutes on foot; five minutes from the Kobuchizawa interchange

Izutsuya is where the Chuo Line meets the mountains. Kobuchizawa is the station travelers change at for Kiyosato and the Yatsugatake highlands, and three minutes from the platform, in a private house built in 1927, this eel specialist has quietly become one of the most‑searched addresses in Yamanashi. The house took its name from a post‑war sweet shop that once stood here; what it does now is its own invention, trademarked as AGED EEL — eel rested before cooking so that its savour deepens, then handled the Kanto way. Tabelog has listed it among the country’s hundred best eel houses in 2024 and again in 2026.

What you eat

The house firms its eel in groundwater drawn from beneath the Yatsugatake foothills, steams it by its own method and finishes it over Kishu binchotan. The signature is the takemeshi: eel and rice served in a length of bamboo that the owner cuts and works himself, eaten straight, then with condiments, then with broth poured over, in the manner of hitsumabushi (¥6,050). A “ninou” version splits the bamboo between glazed kabayaki and plain shirayaki, and there are salt‑grilled and lacquer‑box versions at ¥5,500. In the evening a seven‑course AGED EEL dinner (from ¥15,000, two guests minimum) runs from an eel‑and‑kale salad through jellied eel and shirayaki to the aged eel on rice, with an optional sake‑and‑wine pairing.

The booking reality

This is one of the easier books in the region, and it rewards a little planning rather than a long campaign. The calendar opens 30 days ahead on TableCheck, in English as well as Japanese, and the house also takes the telephone (0551‑36‑5990, in Japanese). Dinner courses and pairings must be booked by 22:00 two days before the visit; a lunch course or a party of nine or more goes through the phone. Set meals can also be walked in for — reviewers report queueing before opening and being given a one‑hour slot — but on summer weekends the eel can sell out and the house closes early, so we would not gamble on it.

A few rules matter. The kitchen starts cooking to your reservation time, so a party more than 30 minutes late without a call is treated as a cancellation; tables run to 90 minutes when busy; courses carry a cancellation fee whose rate the house does not publish; and a no‑show can mean no future bookings. Children are welcome, with four high chairs. For guests abroad, our desk calls the house in Japanese to settle a lunch course or a larger party and to confirm the day’s calendar, which the house posts on its website and Instagram.

Travelers heading up to Kiyosato, Hokuto’s wineries or the Yatsugatake trails who want the first proper meal of the trip within sight of the station — and anyone pairing this with the harder books nearby, since Izutsuya is the one you can add a month out.
