Ian F. Martin is a music writer from UK who has been in Japan and his first book is just out. It's called "Quit Your Band" and its subtitle is "Musical Notes from the Japanese Underground." Sounds interesting, doesn't it? Unfortunately, we don't see the book yet, but it looks really promising.
See the following interview. A must if you are interested in contemporary Japanese music scene.

There is no reference to Hikashu in this interview and we don't know he ever mentioned the band in his book, but in fact he once selected "Ikitekoi Chinmoku" as the best album of 2015.
And this another interview he did mention our beloved band.
