赤湯
The holy land of Delaware grapes — a natural wine hub where Tohoku's oldest winery and boundary-pushing producers share the same hillside slopes.
Akayu, in Nanyo City, Yamagata Prefecture, is a historic Japanese wine region known as the holy land of Delaware grapes. Located on well-drained south-facing slopes in the Okitama basin, the area benefits from dramatic diurnal temperature shifts and mineral-rich soils that produce high-quality, concentrated fruit. Home to Tohoku's oldest winery, Sakai Winery (est. 1892), Akayu now hosts six distinctive wineries. In recent years it has emerged as a vibrant hub for natural wines, led by innovative producers such as Yellow Magic Winery.
Best for: Natural wine enthusiasts and those seeking unique, low-intervention Japanese wines made from Delaware grapes. Also ideal for travellers combining hot-spring relaxation with winery visits.

- Which is the oldest winery in the Akayu region?
- Sakai Winery, established in 1892, is the oldest winery in the Tohoku region and is located in Akayu. It is renowned for producing unfiltered wines without fining agents, staying true to its founding philosophy.
- What style of wines is Akayu known for today?
- Akayu is increasingly known for natural, low-intervention wines — unfiltered, no-added-sulphite, and orange-style whites made from Delaware and other local varieties. Yellow Magic Winery is a leading name in this movement alongside traditional producers.
