Orix Buffaloes On the 26th, the team announced that its farm system player, Jo Endo (Jo) infielder, would be traded to the Yakult in exchange for cash.

He joined Hanshin Tigers in the 2019 draft as the fourth pick. In the offseason of 2024, his fifth year as a professional, he was released from the team, but that same year he recorded the highest on-base percentage of .392 in Western League and the second highest number of stolen base with 30. His stable defense skills, mainly at second base and shortstop, were also highly regarded, and from 2025 he played for Orix Buffaloes as a developmental player. He also tried playing in outfield, saying, "If I can play various positions, I'll be able to play in games," thus broadening his range as a player.

In January 2014, he trained with Masataka Yoshida (Red Sox) in Okinawa. "I want to learn how to connect training to batting and how to use my body. I want to watch Yoshida's batting and absorb more," he said, having spent an intense time with the other left-handed hitter. This season, he was unable to show his true potential in the farm league, batting .174 in 34 games. Nevertheless, he showed an aggressive attitude when he got on base, with 8 stolen base.

Endo expressed his gratitude and determination through the Orix Buffaloes organization, saying, "I am truly grateful to The Buffaloes for taking me in after I was released and for providing me with an environment where I can baseball. However, I am sorry that I was not able to contribute as a player on the first team. I am very grateful to The Swallows for giving me a chance. I will accept this as my last chance, give my best performance, and definitely become a player on the first team."

During his time at Tokai University Sagami High School in Kanagawa Prefecture, he played on the U-18 Japan national team alongside players like Orix Buffaloes Miyagi of Hiroya Miyagi and Roki Sasaki of the Los Angeles Dodgers. He said, "I'm able to baseball while receiving great inspiration from my peers who are active at the highest level," and he has steadily improved his own skills, motivated by their presence. At Yakult, Yasunobu Okugawa, who was also his teammate on the Japan national high school team, is playing as a starting pitcher. This 24-year-old, full of potential, is poised to break through his limitations in his new environment.
