山中慎介引退 Teiken Promotions Shinsuke Yamanaka retiring. Yamanaka and I had our first pro fight the same time and we are both the same age. We were both not elites when we started out but we worked hard endlessly and come to realize Yamanaka had. Successfully defended his @wbcboxing belt 12 times. His personality and his humbleness outshines anyone here at the gym and I’m proud and honored to fight with him during this era. It’s sad to see him leave the sport but as a dear friend I wish my best to Shinsuke and his Family! Great Job Shinsuke! #ShinsukeYamanaka #GodsLeft #TeikenPromotions #Teiken #TeamTeiken #GoldenBoyPromotions #GoldenBoyBoxing #Kamegai #YoshihiroKamegai #CorazónDeAcero #CorazonDeAcero #HeartofSteel #Nike #boxing #JAPANboxing #USAboxing ・ ・ ・ *Posted from Japanese* 慎介引退。 寂しくなるが、これだけの事を成し遂げて来た上に健康な内に辞められる事は素晴らしい。 お疲れ様! #帝拳 #帝拳プロモーションズ #山中慎介 #亀海 #亀海喜寛 #鋼の心臓 #鋼のハート #ネジ飛び Yoshihiro Kamegaiさん(@yoshihirokamegai_official)がシェアした投稿 - Mar 4, 2018 at 2:56pm PST
