Daiichi Juken Group (Daiichi Juken Holdings Co., Ltd., Headquarters/Chuo-ku, Osaka City, Representative Director Takeshi Matsuo, https://www.d-group.co.jp/) announces that it has applied for and acquired the naming rights sponsorship solicited by Osaka City.

Daiichi Juken Group, known for its INOVE series, is a regional company rooted in Osaka, having developed its real estate business for over 50 years.
