Yudai Shigeoka Retires to Support His Brother

Japanese boxing sensation Yudai Shigeoka has made the significant decision to retire from the sport, directing his efforts instead towards supporting his younger brother, Ginjiro, who is currently in a hospital in Kumamoto recovering from serious head injuries. This tragic situation unfurled after Ginjiro, 25, suffered a defeat to Pedro Taduran in May, which led to him being hospitalized following a deterioration in his condition that necessitated inducing a coma to aid his recovery.

Emotional Farewell from Boxing

Yudai, who is 28 years old, has remained a steadfast presence for Ginjiro during this challenging time. He considers his choice to step away from boxing not only poignant but also a privilege, especially in light of the recent tragic incidents within the sport. He took to social media to share an emotional farewell from boxing, stating:

“The other day, my brother Ginjiro was transferred to a hospital in Kumamoto. And today, I, Yudai, decided to retire from boxing.”

Gratitude for Medical Team

Shigeoka expressed heartfelt appreciation for the medical team at National Hospital Osaka Medical Center, recognizing their dedication as instrumental in saving his brother’s life. He shared:

“Thanks to all the teachers and nurses at National Hospital Osaka Medical Center, Ginjiro is still alive. I’m so grateful. He saved my life.”

Supporting Ginjiro’s Recovery

His postings also include details about Ginjiro’s ongoing recovery, emphasizing the effort he puts into rehabilitation. Yudai commented on his brother’s determination:

“I’m currently at a hospital in Kumamoto, trying three types of rehabilitation for three hours a day. ‘Don’t give up, keep going,’ I say every day, and I support him not to put out the flame in his heart.”

A Journey Together

Reflecting on the bond he shares with his brother, Yudai reminisced about their journey in martial arts beginning at the age of six, navigating various challenges together. He stated:

“Silver brought me this far. My dream of silver was big, and I was only halfway through my dream, but I think it’s my brother’s role to color my life from now on. I don’t want silver to regret boxing. Because the people you meet there, everything you experience, is a legacy.”

New Dreams and Aspirations

He expressed his intent to create spaces or events where people can connect with Ginjiro, stating:

“From now on, ‘If you go here, you can meet Ginjiro!’ – make that place. That’s my new dream. The plan is progressing steadily. That’s why I decided to retire. No regrets. This is where the real game starts.”

Lessons from Boxing

Yudai also acknowledged the invaluable lessons he’s learned from boxing and martial arts, emphasizing resilience and hard work:

“Every day I work hard, every day I keep working hard, persistence is strength — in my heart, and I will bloom with silver in my new path.”

Gratitude Towards Fans

Ending his message, he conveyed his gratitude towards fans:

“I’m retiring, but I’d love to see the Shigeoka brothers live. Thank you so much for all your support so far. We will definitely meet again, guys.”

With Yudai stepping away from the boxing ring, the Shigeoka family embarks on a new journey focused entirely on Ginjiro’s recovery. Yudai’s decision speaks volumes not only about family loyalty but also about the harsh realities of the boxing world, where the risk of serious injury is a somber reality.
