To the fans, thank you for supporting for nine years. Even though I missed a full season with a year of rehab, the support from many people allowed me to end my career with no regrets. Please continue to root and cheer for the Tokyo Yakult Swallows.
A very big thank you to the fans that supported me for fourteen years. I was able to get through the good and the bad because of your support. I am nothing but grateful. Thank you.
