In Koshu’s birthplace, a 1941 farmers’ cooperative still ages wine in a 1944 5,000-liter barrel, guided by four Japanese aesthetic ideals.
Honjo Wine traces back to 1941, when 130 grape farmers in Katsunuma — birthplace of Koshu, Japan’s indigenous white grape — formed the Iwasaki Grape Wine Cooperative Brewing Association; it became a stock company in 1952. The winery organizes its range around four Japanese aesthetic themes: wakei seijaku (harmony and tranquility), wabi-sabi, shu-ha-ri and ichigo ichie. A 5,000-liter barrel built in 1944 and an earthen storehouse remain in active use, alongside modern IoT-assisted brewing. Guided tours (about 45 minutes) take in the historic barrel and storehouse, and walk-in tastings offer four wines by the glass.
