This classic of Japanese mountain literature by Kyuya Fukada has recently been translated into English by Martin Hood, a Swiss fellow. I’m almost done with his translators notes ( 40+ pages) and so far it’s a very thorough introduction with lots added to the original content as far as background information. I’ve only climbed two of these peaks (Omine-San and Aso-San) but I hope to summit many more while I’m in Asia and this book already has me inspired and working on my tick list for the coming summer season.
