Aoni Onsen feels like stepping back into the age of the samurai—except you’re far less likely to be killed. That said, I can’t completely rule out stumbling across a wandering bear or slipping on the slick rocks of the mixed‑gender rotenburo outdoor baths. Especially if you’ve had one too many cups of excellent sake, or the dangerously good apple cider Aomori is famous for.
Just don’t tell Yuri any of this. She would hate this place.
Darkness is one of her personal “Three Ks of Doom”: Kurai, Kusai, and Kitanai. Well, it’s not dirty or smelly—but Kurai? Oh yes. Darkness everywhere. “Are you trying to kill me? Do you think I don’t exist? Why are you so selfish—turning off the lights just so you can watch a movie in the living room?”
Fair questions.
Well, given there is no electricity to turn on the lights, let’s turn our attention to dinner.
The river fish here is outstanding. You eat it straight off the stick like a drumstick—crispy salted skin, bones included, and even the tail, which has the texture of potato chips. If you want to remove the bigger bones, you can… but honestly, in the pitch‑black dining room, no one can see what you’re doing anyway. You can pretty much do whatever you want.
Dinner involves lighting your own candle to cook the hotpot, which feels like having a personal campfire. You decide how rare—or well done—you want your meal. The homemade pickles and vegetable‑heavy dishes make this one of the healthiest nights out, though sitting cross‑legged on floor cushions may require a physiotherapist for some people. Thankfully, I didn’t witness any emergency stretching sessions during my stay.
Each dinner dish is introduced rakugo‑style by the chef—equal parts storyteller and aspiring stand‑up comic—but only in Japanese. In fact, almost everything is in Japanese, except for the crucial sign reminding you to “wear brown slippers to go outside.” Having some knowledge of the Japanese language definitely helps. Miso soup and rice are served from a central table, buffet‑style, and the soups vary between breakfast and dinner.
Breakfast is where things really shine. The highlight is a delicate fish served with a plum‑like sauce—sweet, savoury, and just a little tart. You can eat the entire thing, head and tail included. Even the poem on the seaweed packet perfectly captures the spirit of the place: living in harmony with mountains, rivers, forests, and sky.
I can easily imagine Japanese culture students—or parents desperately needing to detox—falling in love with Aoni Onsen. There’s a monastic, dormitory‑like rhythm to the place: everyone eats the same meal at the same time. It’s basic, but not spartan. Unlimited rice and soup help, as does an excellent selection of beer, wine, and spirits—especially the sake and apple cider, which beautifully preserve the sweetness of Aomori apples. Prices are very good compared to most developed countries. Picture a small bottle of sake for under 1,000 yen.
Above all, there’s a genuine sense of community. When a long‑time staff member returned for a visit, she received a rousing welcome. And in a place this dark, that kind of warmth really stands out.
