The Tohoku region is known for its beautiful mountains, delicious rice, snowfall and hot springs. What better way to enjoy all of the above than at a ryokan (Japanese inn) that can provide access to these Tohoku treasures?
Within the onsen, or hot spring, realm is a rare and dying breed of bath — konyoku. Konyoku onsen are mixed gender baths that have been around for hundreds of years. As time went on and cultures mixed in Japan, new laws have made it harder for these ancient establishments to continue their traditions. What was considered normal in Japan was considered lewd and inappropriate. Therefore, Japan changed her ways to better fit the conservative palate of the international society. Whether you are bathing with your significant other or a group of friends, keep a part of Japan’s old culture alive by visiting one of the Tohoku region’s many konyoku onsen.
1. Aoni Onsen
青荷温泉本館を出てすぐの健六の湯。総ヒバ造りのお風呂と窓が多く開放的で明るい雰囲気が個人的にどストライク！(*ﾟ∀ﾟ*) とっても気持ちいいっ！夜入ったにもかかわらず、早朝さらに入湯。ラッキーなことに貸切状態だったので、のんびり入らせて頂きました。外に出ると大釜のようなお風呂と露天風呂がありました。お湯はぬるめでしたが、記念に入ってみました。看板もツボ！( ´∀｀) #散策 #東北 #青森 #黒石 #青荷温泉 #ランプの宿 #健六の湯 #レトロ #ランプ #温泉 #秘境 #宿 #露天風呂 #ヒバ #旅 #行くぜ東北 #春の東北 #japan #tohoku #aomori #kuroishi #aonionsen #onsen #hotsprings #travel #vacation #ramp #retro #landscape #inn
Longing for a magical, off the grid getaway? Aoni Onsen, also known as Lamp no Yado, is the place for you.

After a four-kilometer hike through the mountains in Fukushima, you will stumble upon a natural onsen in its purest form. There is no establishment and the bath itself is just a river with hot water spouting from the activity of the earth’s geothermal insides. Visitors must be careful, for part of the river is sometimes closed due to high levels of toxic gases produced from the hot springs. Though bathing suits are allowed in this bath, going fully nude is recommended due to the high acidic levels of the water that are said to be nourishing to the skin. In fact, the pH level of the water at Numajiri Onsen is 1.9, which is the same as lemon juice.
