"Groupthink: Why Did the "Excellent Men" Go Astray?" Fumitake Koga Price: ¥1580 The obi (sleeve) has a tear (see photo 5). Other than that, I think it's in good condition. Only read once after purchasing new. No price reduction is possible for this item. #FumitakeKoga #Fumitake_Koga #book #society/general
