How to Wash your Hanten

“Do I have to have my hanten dry cleaned?” is a question we sometimes get here at Japan Store. Fortunately, the answer is no. But if you just stick it in the washing machine, it will suffer some damage, especially to the cotton padding. And of course the insulation quality of the padding is a major reason why you wear the hanten in the first place, right? So read on and we’ll explain how a few simple steps can ensure that your hanten stays warm and clean for years to come.

Wash a hanten1. With the hanten folded as shown in the photo, handwash in a sink or large basin. Gently push it into the water until it is soaked through, and remove any obvious dirt and stains. Use cold or warm water and a mild (neutral) detergent. Bleach is a definite no-no.

Wash a hanten2. Without squeezing too vigorously or stretching the fabric, drain the water from the hanten. Place in a laundry net large enough to hold the folded hanten as shown.

Wash a hanten3. Use your washing machine’s spin feature to drain most of the remaining water from the hanten. Use the shortest spin cycle setting. Ensure that you do not use your washing machine’s dryer feature if it has one, as this will damage the cotton padding.

Wash a hanten4. Hang out to dry, outdoors if at all possible and as shown in the photo. The more the hanten is spread out, the better it will keep its shape and the less likely that the cotton padding will dry in clumps. Hang until the outer fabric is dry, then turn over to expose the inner lining and allow to dry fully. This will ensure that the cotton padding dries and retains its volume.

Wash a hanten5. If you must dry the hanten on a hanger, make sure it is a rounded type and not a skinny type as shown. Again, this will help the hanten maintain its shape and prevent the padding from drying in clumps.

Occasional washing as described above will ensure that your hanten stays as warm and stylish as the day you bought it. See our selection of mens and ladies hanten.


The Ideal Winter Jacket

If you’re thinking of splashing out on a down or fleece jacket this winter, you might want to think again. For a century and a half the humble hanten has been a staple of many a Japanese wardrobe. And some recent research by one of the country’s top hanten makers illustrates just why that is.

For several years here at Japan Store we have carried hanten made by Kuwano Shinken Sangyo, who market their handmade jackets under the brand name Watanosato (“The Home of Cotton”). They come in a variety of traditional patterns and comply to the strict specifications that allow them to be classified as Kurume Kasuri and distinguish them from cheaper hanten, mostly made in China. One specification is that the padding must contain at least 50% cotton. Watanosato hanten contain 70% cotton, with 30% polyester to ensure the padding keeps its volume and insulation qualities for many years of use. So just how warm are they?

Hanten Jackets

The company carried out tests to compare the insulation qualities of three types of jackets. They used one of their own hanten and compared it to a fleece jacket and a down jacket, both from popular brand Uniqlo. With an ambient room temperature of about 15 degrees Celcius, skin temperature was measured both before and while wearing the different jackets for a period of 30 minutes using a thermographic camera. The image below shows clearly that the hanten keeps you consistently warmer (for geeks, the table of data is at the bottom of the post).

So this winter try on a traditional hanten and enjoy the warmth that has insulated Japanese people for over 150 years. See our selection of mens and ladies hanten.
