Its not the book, and I never expected it to be, even says in EP1 'based loosley', not World War Z kind of 'loosley' at least..
I wish they would do the Book as a documentary with interviews etc.
Law & Crime in Japan is pretty fascinating, because of the cultural differences. I did work in Tokyo for a corporation that owned a lot of night clubs in Roppongi. I drank a bunch of nights in one of their clubs that was later famous for having one of their imported White 'hostesses' abducted and murdered by Japanese millionaire who was one of her regulars. Joji Obara - Wikipedia
I saw the whole 'Hostess' Club scene up close and personal when I was there and dated a 'J-Girl' who worked at the flagship one for the company. A lot of money gets thrown around in those places. Many a yen from Corporate expense accounts goes to buying pretty white foreign girls drinks and gifts in hopes of Salaryman getting in their panties. Eastern Euro and Israeli chicks on the circuit will give it up for the expensive Gucci gifts, US and Aussie girls will not usually and know the game is aabout stringing the dudes on a long as possible, and perpetuating the fantasy. 2 yrs Hostessing in Japan and living on the cheap and saving it up and let the girls walk away with a couple hundred grand if they can keep guys on the hook forever with 'one day maybe I'll let you do me'. Even weirder is they have Male Host clubs where anime looking femme dudes wait on uggos all night and fleecing them the same way.
I guess it all goes back to the ancient Geisha culture in a weird twisted way.
I downloaded the book yesterday based on your reviews and because I'm enjoying the show so far. I noticed on the comments for the torrent that one guy said it's highly fictionalized
Didn't start it yet but had a look at first few pages and something about the language felt off. The show has a serious tone, whereas the book felt a bit "softer", maybe that's just the intro?
I also note in the book he has a family, whereas the show is obviously different
