MugiWhat, beer sleeps underground? Mole-matured beer sounds so wild that I want to dig a tunnel before drinking it!
Hop BroNearby Doai Station is known as Japan's “mole station” because its underground platform is down 486 steep steps. That's where the kegs are stored and matured.
MugiFour hundred eighty-six steps?! My legs would start hopping before the first sip! But what does underground maturation actually change?
Hop BroThe underground platform tends to stay at a steadier temperature, helping beer settle gradually. That means you can taste the flavor changes from aging.
MugiSo the beer gets a chance to mellow underground? Do the kegs stay down there until the event?
Hop BroThey are scheduled to bring the kegs up on the event morning. So the crew faces kegs versus 486 steps—this is a beer event with serious cardio!
MugiCarrying kegs up 486 steps?! I'll cheer from the top while holding my glass. That would make every sip feel extra precious!

MugiBeer and cider too—Minakami's goodness all in one place! The event runs from noon to 6 p.m., with food and live music as well, right?
Hop BroExactly. Advance tickets include either an original glass or a sticker, and day-of tickets are planned too. I want a one-of-a-kind local pint with the station's story behind it.
MugiIt sleeps underground, climbs 486 steps, then lands in our glasses—the story itself sounds delicious! I already want to toast with mole-matured beer!
Octone Brewing, based in Minakami, Gunma, will participate in Mogura Beer Camp 2026 on Saturday, October 3.
The event will take place at DOAIVILLAGE beside JR Doai Station on the Joetsu Line. Doai Station is known as Japan’s “mole station” because its lower platform lies underground, reached by descending 486 steps from the station building. The event will feature “Mogura Aged Beer,” beer matured in that underground environment.
According to Octone Brewing’s announcement, the beer casks will be brought up from the underground platform on the morning of the event. The 486-step journey to the surface is part of the story: visitors will be able to taste beer that has spent time in a distinctive, relatively stable underground setting.
Mogura Beer Camp is scheduled to run from noon to 6 p.m. Alongside craft beer and food, the program is expected to include live music and beer-related activities. Advance tickets are available with either an original event glass or a sticker, and same-day tickets are also planned.
Octone Brewing makes beer using the water and natural resources of the Okutone area. Its brewing project began in 2018 and has since expanded into local agriculture, including hops and apples, as well as hard cider production. After expanding and relocating its brewing facilities in spring 2025, the brewery has continued producing both craft beer and hard cider.
At Mogura Beer Camp, the underground setting, Minakami’s natural landscape, and the character of a slowly matured beer come together in one experience. For beer lovers, it is an opportunity to taste not only a limited beer but also the place and story behind it.
