The Hakkaisan Brewery Group, which produces Hakkaisan, has refreshed its on-site uniforms into three styles with support from ID UNITED ARROWS. The project pursues both functionality and design.
The new uniforms are being completely refreshed for use by the Hakkaisan Brewery Group at its work sites. UNITED ARROWS' corporate uniform business, ID UNITED ARROWS, is participating as a partner.
The uniforms were developed over approximately 2 years from the initial concept, through repeated prototyping and improvements. The three new items, a blouson, pants and polo shirt, provide the functionality required for sake brewing and distilling while offering designs suitable for wear outside the workplace as well. At Uonuma no Sato, where the breweries are located, visitors have opportunities to see the brewers, so the aim is to create clothing that feels approachable and appealing.
The project also draws on mutual understanding built through previous collaborations, including the development of a collaborative sake under the sake brand 唎酒 Rishu in 2025.
