5 Japanese Ways to Keep the Body Warm in Winter

Keeping your body warm in winter can be a struggle, and being in Japan is no exception. Its chilly temperatures depend on the region. You can get milder temperatures in southern Japan, whereas temperatures in northern Japan can plummet to sub-zero temperatures.

Despite this, the Japanese know how to keep their bodies warm in winter. They have adapted to the freezing weather and even use minimal energy and resources to keep themselves feeling snug.

Engawa

A traditional Japanese house has an engawa surrounding its edge. It resembles a sunroom to capture most of the winter sunlight. The heat is transferred to rooms nearby, keeping their occupants warm throughout winter.

An engawa is a strategic form of Japanese architecture, as it is built according to the seasons. It keeps you warm in the winter while also letting the breeze in during summer.

During summertime, on the other hand, the engawa doubles as a front porch. The doors slide open to let the summer breeze in. This type of architecture is very strategic as it allows adjacent rooms to be warmer in the winter and cooler in the summer.

Kotatsu Table

Kotatsu is another brilliant Japanese invention to keep your legs warm. It is a heater tucked underneath a low table, which is then draped with a futon or a thick quilt. Japanese people tuck their legs under the kotatsu blanket as they enjoy tea, read a book, or watch television. It keeps them warm and even makes for a cosy sanctuary to nap.

Kairo

Kairo, also known as pocket warmers

If you want to keep your body warm in winter quickly, kairo is a quick way to provide you with warmth.

Kairo is essentially a pocket warmer filled with a gel-like substance, which heats up when you snap it. There are various types of Kairo—you can keep them in your pockets, stick them in between layers of clothes, or even store them in your shoes. Many eco-friendly versions are available, where Kairo can reactivate them in boiling water for reuse. Kairo is a convenient tool that offers warmth and is available throughout Japanese convenience stores and pharmacies.

Winter Food

Cold weather in Japan calls for food to keep the body warm. This includes winter specialities, such as a Nabe hot pot, a warm bowl of Oden, or ramen.

Nabe is a Japanese-style hot pot with various ingredients like meat, vegetables and tofu cooked in a broth of your choice. This customisable dish is served in the same pot it was cooked in, with the stove still burning to ensure every bite is warm. In some Japanese supermarkets, you can find a section set aside for these nabe ingredients, which are already packed for convenience.

Another winter classic is Oden—a pot dish in a soy-flavoured dashi broth. It is usually eaten with various ingredients like radish, fishcakes, Atsuage, or deep-fried tofu and boiled eggs.
