You don't even need underwear with this one piece!?
These "Tono Pants®" allow you to go without underwear from the moment you get out of the bath until you wake up the next morning. The inner trunks, carefully crafted from high-quality domestically produced cotton, ensure breathability and prevent stuffiness. They are recommended for when you want to feel relaxed and comfortable after a bath or sauna when your blood is circulating.

You don't need restrictive underwear while staying at home, teleworking, or sleeping. It's not see-through, so it's fine for quick trips to the public bath or convenience store. When you get back, just go straight to sleep. You can spend the night comfortably.

A completely new feeling of not being constricted by anything. Once you wear them, you'll definitely want to tell someone. These are the fun and well-balanced pants®. Please come and experience them in stores.

The Mitsukoshi Isetan Sauna Club introduces their favorite items from the Totonou Pants® line.

Members of the "Mitsukoshi Isetan Sauna Club," established within the Mitsukoshi Isetan Group, will explain the appeal of "Totonou Pants®" through their personal items.

Mitsukoshi Isetan Sauna Club
Founded in the winter of 2020 by four sauna enthusiasts who work at Mitsukoshi Isetan Co., Ltd.
With the slogan "Turning your passion into your job" and "If it's not fun, it's not a sauna. If it's not fun, it's not work," the club engages in information exchange using internal communication tools, socializing in saunas, and also plans events and products. Members are located all over Japan, from Fukuoka in the west to Hokkaido in the north, and their connections through saunas are expanding.

These pants offer a new experience: you feel like you're not wearing anything even though you are . I've worn every type that's been sold since its initial release, and they're all so comfortable that I can't help but exclaim, "These are the best!" Many people wear them when going to public baths (saunas), but personally, I recommend wearing them to bed. You'll be surprised at how comfortable they are to sleep in!

Wearing the Totono Pants® after a sauna on a Fukushima holiday will make your ultimate relaxation time even more comfortable. The routine of sauna → cold bath → fresh air is said to be the way to achieve "totono" (a state of perfect relaxation), but a drink after the sauna is also a special moment of "totono." How comfortably you can spend that moment is important. That's where the lightweight and non-restrictive Totono Pants® come in handy. Not only are they great for after the sauna, but I think they are also a versatile item that will be useful as relaxing wear in the coming seasons.
