I'm marking it as not recommended, simply because I personally find it as dull as dish water. I can appreciate that Japan being magpies love to adopt other cultural aspects, but being British, there is nothing so dull as reading about the class system in this country. So far, there has been no real protagonist, just a collection of snooty people sat around drinking tea. No other story has presented itself as yet. Japan may well be fascinated about etiquette and manners and may well lap this up, but if you are obsessed with this topic, it may be right up your street, but forme... it is a hard pass.
