GRANDLINE BREWING marks three years of culture-driven craft brewing in Yokosuka

GRANDLINE BREWING, a craft brewery based in Yokosuka, Japan, is approaching its third anniversary in October 2026. Founded by Hayato Onishi, the brewery aims to function as a ‘communication brewery’ that connects people through the culture of beer.

Located in a city influenced by both Japanese and American cultures due to the presence of U.S. military bases, the brewery focuses on styles like American IPA. Beyond brewing, the company integrates various cultural elements including music, art, fashion, and Web3. Notable initiatives include the production of ‘Crypto Beer’ for an NFT-based beer community and the development of ‘MetΔBrews,’ a virtual brewery concept designed to bridge real and digital experiences.

Onishi emphasizes the importance of branding and marketing to expand the reach of craft beer, noting that the business must move beyond mere production to achieve widespread recognition and commercial success.
