I love Japan. I love their inventions.
Japan Trend Shop.com featured Samurai Warrior Underwear and is based on the design of armor samurai.
The sales pitch is truly fantastic, "Whether you're a warrior in the boardroom or the bedroom, make your underwear match your samurai spirit with our world-exclusive Samurai Underwear." a cotton, polyester and polyuethane mix which claims to be breathable, wicking and itch free which is always good.
