Book on "Origins of the Gravitational Wave"

Kotaro Kyutoku (Assistant Prof. in KEK and iTHEMS visiting researcher. Former iTHEMS SPDR) has published a book "Origins of the Gravitational Wave" in Japanese with Masaru Shibata (Max Planck Institute and Kyoto Univ.).
It contains excellent explanations on general relativity and black holes, structure of neutron stars, supernova explosion, gamma-ray burst, gravitational wave, mergers of black holes and neutron stars, and current/future gravitational wave detectors on earth and space.
Everybody who is interested in GW should have one in his/her bookshelf. English translation will be called for.
