But this album is not released by Cragale not HG Fact like bit-well-known label, and it's from Dakimyouga Records, Discogs says this is only released album by Dakimyouga, but catalog number (DAKI-2200) and style of album packaging and release on Flexi Disc, I think there's more albums from this label in Japan somewhere, or if I super lucky in Korea (Since I found Hiroshi Yoshimura's album, and private pressing albums, only promo released album from CBS/Sony and Vacant World by Jacks in Daejeon).
So, as you think, this album is one of 80s Post Punk album from Japanese Indie band. Guitar and Drums made think about Para-Phrase mixed with Idiot O'Clock, and Vocals are... bit reminding me of Jun Togawa with lower tone.
