Tsumagoi Kogen Brewery to host a 30th anniversary all-you-can-drink beer course on June 20-21
Tsumagoi Kogen Brewery in Gunma Prefecture will mark its 30th anniversary with a special two-day course on June 20 and 21. The event pairs all-you-can-drink draft beer with six dishes, and reservations are accepted by phone.
Hop BroThis one jumps out immediately. A 30th anniversary special course is happening on June 20 and 21, and it centers on all-you-can-drink draft beer.
MugiWait, all-you-can-drink draft beer for 3,500 yen already sounds dangerously appealing, and now you're adding anniversary energy too?
Hop BroThe venue is Tsumagoi Kogen Brewery Restaurant in Osasa, Tsumagoi, Gunma. It's a self-brewing microbrewery known for using hops it grows itself.
MugiMicrobrewery? What does that even mean? A tiny beer factory I can carry around in a tote bag?
Hop BroPretty much, it means a small-scale brewery. They grow hops, brew on site, and serve it there too, which is exactly the sort of thing beer nerds lose their minds over.
MugiOoh, and this includes every draft beer on tap that day, right? If the beer names are a surprise, that makes it feel like a treasure hunt.
Hop BroExactly. The beer names and styles are basically part of that day's tap lineup, and since draft service inside restarted in April 2025, the timing feels especially good.
MugiAnd it's not just about drinking, either. Six dishes included is serious work: cabbage salad, sausages, beef stewed in beer... my stomach is already making the reservation call.
Hop BroIt stays pretty limited too: only eight groups per session, with seatings at 11:00 and 16:00, phone reservations only, and parties of two or more. There's even a 2,500 yen soft-drink option for drivers.
MugiWhen you say they've spent thirty years connecting farming, brewing, and serving, local ingredients hit harder somehow. It stops feeling like just a deal and starts feeling like a celebration.
Hop BroRight, and even with regular restaurant service paused, it comes back as a beer-first anniversary event, which feels exactly right for this brewery.
MugiI'm sold. I want to start with a homegrown-hop pint and make it all the way to dessert. Reading this made me want a glass immediately.
