I'm aware of the concepts loosely but am interested on if theres any good reads/books which have explored this in depth.

I'm relatively unfamiliar with japanese philosophy and aesthetics in general and haven't read any books on it so if there isnt a good starting point in relation to aesthetics I'd be interested in that as well

I was interested in this too and I downloaded the book of five rings, didn't read it yet but it might be what are you looking for

From my understanding that book is primarily based around sword fighting and has a philosophical angle to it. I guess concepts like wabi sabi, mono no aware, yugen etc. May pop up in it but wouldn’t be a focal point.

Those 3 things are what I refer to as Japanese aesthetics. From recollection wabi sabi is the pillar basically

This one looks amazing, dunno if I will buy yet or get someone to cop this for me as a gift:

I saw this one first on amazon but was a bit skeptical because I feel like western writers fetishise often when looking at oriental and middle eastern history/philosophy. Looking into the author tho he seems pretty legit, probably will buy this one.

and this one seems more indepth but good:

Look for books about wabi sabi

no, Donald Richie is good. That's the only one you need.

@pmfer as dude posted above, Tanizaki - in praise of shadows.

only like 40 pages, classic essay by japanese lit icon re: japn aesthetics. that is what you need first and foremost.
