Tokyo is a crowded city. Its rooftops represent valuable space, and they're used in some very creative ways. This time on Japanology Plus, our theme is Tokyo rooftops. Our main guest is Kurakata Shunsuke, an architectural history specialist from Osaka City University. He takes us on a tour of amusement parks, gardens and other unique rooftop spaces. We also meet photographer Takano Akira, who shows us his favorite city rooftops. Along the way we discover rooftop shrines, rice fields and many more surprises.
