In an Instagram post on April 17, 2026, Japan Craft Beer & Wine GRILLMAN in Nishiki, Nagoya, announced that it will hold the event "Oyama Ichimon-kai" starting at 3:00 p.m. on April 25. The post mentioned the participation of the three breweries `@daisen_brewery` `@okdkomincbrewing` `@bishu.brewing`, and said the beers on tap were "mostly decided."

GRILLMAN is a beer pub where you can enjoy Japanese craft beer, cider, and Japanese wine by the glass. In the Fushimi and Marunouchi area, it is known as a place where people can relax over food and drinks. It has a welcoming, easy-to-drop-in atmosphere, which makes it a good fit for gatherings centered on craft beer.

This post also noted that the shelves in the shop's passageway were being cleared out. There was also a call for people who want to place hobby items, decorative pieces, or creative works there, and it was easy to see that a corner of the store is gradually changing. That mix of everyday updates and event announcements in the same post is very much in keeping with the shop's style.

On the day of the event, bingo, limited menu items, and opportunities to interact with the brewers are also planned. Although no specific beer names were listed in the post, there is still plenty to look forward to as a tasting event bringing together three breweries. Anyone hoping to enjoy craft beer in Nagoya will want to save the 3:00 p.m. slot on April 25.
