Your review is very misleading.
It's Indian, not Japanese. Although it has found strong ideological footings in Chinese and Japanese historical backgrounds, Buddhism (as is the album's thematic dialogue) actually originated from India.
The album is therefore largely influenced by Indian culture, and Bajka herself hails from India. It's evident even in the instrumentation. If this album were a soundtrack, it'd be more suited for a Diwali festival than a Chanbara flick.
Before reading this review I never noticed that the album does branch out a little midway through (a few songs have been distinctively interspaced with genres more familiar to those of the house music diaspora), but I think you might've found it a little more enjoyable if you had been accurate about the album's influences to begin with.
