No.505 Hiroshima Winery is a small-scale, natural winery located in Hiroshima, Japan, founded by winemaker Shingo Oto. The winery is known for its bold commitment to minimal-intervention practices, producing wines that reflect the natural character of the grapes and the surrounding environment. All fermentations are done with wild yeasts, and no sulfites are added at any stage of production.

The wines of No.505 are playful, expressive, and deeply personal. Each cuvée is crafted with intention and named with affection—bottles like “Dad,” “Mum,” “Lullaby of Hiroshima,” “Midori-chan,” and “Yes, backflips” reflect the human stories and creative spirit behind the winery.

The style is vibrant, often experimental, and always unfiltered. Wines include reds, whites, rosés, and orange wines—each one a living product shaped by season, fruit, and philosophy.

Though based in a lesser-known wine region, No.505 Hiroshima Winery has drawn international attention, participating in natural wine fairs such as RAW WINE. Their work contributes to the growing recognition of Japan as a serious player in the global natural wine movement.
