Hoshino Onsen Tonbo-no-Yu (星野温泉 トンボの湯)
If you don’t mind bathing with strangers, a great way to rejuvenate at the end of the day is to indulge in a hot spring. Established in 1915, Hoshino Onsen Tonbo-no-Yu is known as an onsen that makes your skin shiny and soft. Many celebrities and famous writers in the past would utilize the facility when they visited Karuizawa.

Amongst all the bathtubs, the one made of Japanese cypress has a depth of 90cm, allowing your shoulders and body to be soaked in the hot spring. The scenery beyond the floor-to-ceiling window also makes the bathing experience even more amazing. In winter, it would almost feel like you are bathing amongst the snow!

Picchio Visitor Center (ピッキオ)
Not far from Tonbo no Yu, there is a visitor center by the Kera Pond (ケラ池). In fact, Picchio is more of a local wildlife research center. The center, established to protect nature, holds various tours into Karuizawa Wild Bird Sanctuary.
Knowledgeable staff will guide you to wild nature and introduce you to the ecological system of Karuizawa, the fun facts, and its wildlife. In addition to just walking around in the forest, the guide will likely also be showing you videos and photos to make the entire session a lot more informational.
Besides the daytime tours, nighttime tours are also conducted, allowing you to spot nocturnal animals such as flying squirrels. Before stepping out into the wild, a small lecture about flying squirrels and the tips of spotting squirrels are held indoors. So when you are in the forest, you will know exactly what to look for. Because Picchio knows the flying squirrels’ active time, the spotting rate of these cute animals is close to 100%!
And don’t worry about walking through the dark forest. You will be boarding a special vehicle that makes exploring the forest at night easy.
If you are interested in seeing the flying squirrels, you can book the tour HERE!
Picchio Visitor Center also has a cafe facing the pond where you can grab a nice cup of coffee.


In the colder months, the pond in front of the cafe becomes an outdoor ice rink (Kera Pond Skate Rink, ケラ池スケートリンク」) where you can enjoy ice skating. The pond in the forest, where many wild animals reside, is one of the best spots in the area to enjoy the winter sport.
