On the 21st, Lotte announced that the registered name of Daisei Tanaka, who was drafted 7th, will be "Daisei."

Yamato commented through the team, "Since the surname Tanaka is common, I have always wanted to be called by my first name, and the kanji for Yamato are rare, so I asked the team to register me with my first name, which is easy for fans to remember and call, with my own feelings in mind. I would be happy if you could call me 'Yamato', and I will do my best to perform so that this registered name will become well known."

The name on the back will be "YAMATO."
