16. Japanese preference for Sauna Hat
User’s Voice A（30 year old male）
- High-temperature saunas can damage hair.
- I usually wrap a towel around my head to protect my head and hair from heat.
- I am concerned about publicity in the sauna room. If everyone else is wearing one, I'll
wear one, but I don't want to wear one that stands out in places where I'm not.
-I don't want to wear something that stands out in places where people aren't wearing
it. When I soak in the hot water or wash my body, I wonder, "Where do I put my sauna
hat?" I'm not sure where to put the sauna hat.
-It is a hassle to wash it. Wool or felt material is recommended to be washed by hand,
so it's a bit of a hassle to wash it every time.

17. Japanese preference for Sauna Hat
User’s Voice B（20 year old male）
- I also have a sauna hat and try to bring it to sauna events. Especially in tent
saunas, my head gets very hot.
- However, I rarely use a sauna hat because of the extra baggage and the hassle
of washing it.
- If I want to meditate today, I bring a sauna hat that I can wear deeply because in
a regular sauna it is often too bright to concentrate.

18. Japanese preference for Sauna Hat
User’s Voice C（20 year old female）
- Sauna Hat design should not be too flashy and can be used on a daily basis.
- Sauna Hat is for everyday use and for sauna events.
-I have many kinds of Sauna Hat, but in the end I concluded that it is convenient to
wrap a towel around my head.
- I want the Sauna Hat to have the following features: it should not smell bad, and
it should be able to be worn deep enough to cover the face well.
-Women are often seen wearing Sauna Hats in public saunas. In cities, about half
of the patrons wear them, and in rural areas you don't see them wearing them.

19. Japanese preference for Sauna Hat
User’s Voice D（20 year old female）
- I don't think I would buy Sauna Hat if the design is not cool no matter how good the features are,
and I wouldn't buy it if the design is cool but the features are not. Function is more important, but
design is also a consideration.
-I don't carry Sauna Hat in my daily life because it is a hassle to carry around and wash it.
-I don't carry a sauna hat in my daily life because I don't want to have to carry it around and wash it.
-I have long hair, so I wear a hair bun in the sauna, but the size of the hair bun does not fit the
Sauna Hat, so I have a problem with it floating around.
-I often lose my Sauna Hat, so I would appreciate a reasonable price.
