This is an old book, first published in 2016, but it was shocking and I've reread it many times. Size: 25.5 x 18.3 cm, thickness 1.3 cm. This book provides hints as to why people face financial ruin in old age and whether Japan's pension system is sustainable. The cover has a small tear, the book shows its age, and there are minor stains, but please only purchase if you are okay with this.
