"The Book to be Reborn at 30: Becoming a True Adult" Kazumi Yasui Price: - Out of print. I finally found a good condition copy on Amazon after searching for a long time. I learned a lot from Kazumi Yasui, the original "good woman." Will be shipped via Mercari convenient delivery. I am very sorry, but please refrain from comments asking for a price reduction. #KazumiYasui #Kazumi_Yasui #Book #Ethics/Morals/Ethics/Morals
