On the 16th, the Orix Buffaloes officially announced the acquisition of 18-year-old infielder Chang Yi-An, a member of the U-18 Taiwan national team, on a developmental contract. His uniform number is 153. He served as captain during the 14th U-18 Asian Championship held in Taiwan, where he primarily played as a short stop and recorded a .444 batting average with 6 RBI across six games. The team has highly evaluated his potential and future prospects as a two-way player who also serves as a pitcher.

Furthermore, it was announced that pitcher Hsu Chen-Wei (18) from Taiwan has been acquired as a developmental player. His number is 131. He is a power right-hander whose weapon is a fastball exceeding 150 km/h, and he is expected to be a future candidate for the starting rotation.

In the 2024 off-season, the team acquired Chen, who graduated from the same Kuu Pao Commercial and Industrial High School as Chang, on a developmental contract. In his second year with the team this season, he earned a spot on the 70-man roster and made his first-team debut. Aiming for next season after finishing in the bottom half of the standings for the first time in two years, the club plans to actively introduce specialized motion analysis equipment at their facilities in Maishima, Osaka. They intend to strengthen their roster by scouting talent both domestically and internationally.
