Just like the West has Long Johns, long underwear invented some 100 years ago, Japan has had Suteteko (すててこ). Suteteko date back to the Meiji period (1868-1912) and were initially worn under kimono or hakama. When Western style clothing came in vogue, they were worn under pants, or used as home wear.
They have become the stereotypical Summer item in Japanese popular culture. Lots of Japanese movies, anime and manga feature men wearing the comfortable but oh so unfashionable Suteteko. In the Japanese mind they have become part of the image of the Showa Period (1926-1989).
The public image of Suteteko
This is now undergoing a drastic change. Suteteko are making a dramatic comeback, and have become ultra cool among the young, both guys and girls. The comeback consists of two steps: a completely new word, Iketeko (イケテコ), made from combining iketeru (hot) with suteteko, and up-to-date designs and materials. I have even seen Iketeko that had an image of faded jeans printed on them, complete with holes.
These modern day Long Johns are so cool, you can wear them as outerwear or swimwear without anybody realizing you are out in your undies. An additional benefit is that they absorb your sweat and thereby protect your pants. It is a great way to save money on expensive dry-cleaning.
A true coming out for a fashion item that has been kept in the closet or under wraps for way too long. Go get your Iketeko!
I found some great Iketeko on the online shop of steteco.com:
