"Inner Breathing Exercise" Rina Watanabe Price: ¥1760 I purchased this new on Amazon, but after flipping through it, I found that the content was mostly familiar to me, so I am selling it in excellent condition. Although listed as new, please understand that this item has been in someone's possession before purchasing. #RinaWatanabe #Rina_Watanabe #Book #Lifestyle/Sports & Physical Education
