Very Strong Heating in Winter

The heating in trains and department stores is too strong; it is freezing outside, but you get sweaty inside.

Winters in Japan can get quite cold depending on the region, but what surprises many travelers is "the intensity of indoor heating." Trains, subways, department stores, and restaurants are often well-heated, and it is not uncommon to feel warm enough to sweat indoors even though it is freezing outside.

Especially on commuter trains, combined with the large number of people, it can feel quite hot. If you get on a train wearing a thick coat, you may start sweating in a few minutes, and many travelers feel that "the temperature difference between outside and inside is extreme." Therefore, for winter travel in Japan, clothing that is easy to put on and take off becomes very important.

Also, Japanese people tend to value measures against the cold, and there are quite a few places that set the heating to be "a little hot." On the other hand, there can be large temperature differences depending on the building, so the sensible temperature changes every time you move. By skillfully adjusting your scarf and thin innerwear, you will be able to enjoy winter in Japan more comfortably.
