In a Japanophiles interview, Peter Barakan meets Marty Friedman, a legendary guitarist from the USA. As a member of a well-known heavy metal band, Friedman toured the world. But a deep love for Japanese music led him to move to Tokyo. He went on to perform with major J-pop artists, and in 2016 he became an official ambassador to Japan Heritage. Friedman takes us through his journey, and explains what it is about Japanese music that he finds so appealing.

Tatami mats are a quintessentially Japanese flooring material. They're made of rice straw, covered in woven soft rush. This gives them just the right amount of give, and a fresh natural fragrance. Tatami rooms are used for eating, sleeping and relaxing. They're also important for the tea ceremony and martial arts. Our guest is Koshima Yusuke, one of Japan's leading young architects. He talks about the positive qualities of tatami, and discusses potential new uses in the modern era.
