Oni -- Japanese ogres -- appear to be halfway between humans and beasts, with animal horns and scowling expressions. They come from ancient folklore, but are a big part of modern Japanese society, both through stories, and seasonal events like Setsubun. Many are feared, but others are respected as deities who can control natural phenomena such as wind and lightning. Our main guest is Kazuhiko Komatsu, a leading folklore researcher. He tells us why Oni are more than just terrifying monsters.

After studying English literature and philosophy, Peter MacMillan moved from his native Ireland to Japan to become a university lecturer. He wrote the first full English translation of the Hyakunin Isshu, a collection of classical Japanese poems. In a Japanophiles interview with Peter Barakan, MacMillan explains the intricacies of translating ancient Japanese into English. He talks about the appeal of Japanese poetry, and how he's bringing it to a wider, global audience using games and art.
