花ざかりの君たちへ (2007) | Ryutsu Keizai University — Ohsaka Gakuen’s Gym, Cafeteria and Rooftop

Several school interiors in the 2007『花ざかりの君たちへ〜イケメン♂パラダイス〜』 were filmed at Ryutsu Keizai University’s Ryugasaki Campus rather than at Ushiku Chateau. A detailed 2007 location record places the episode-1 gym where Sekime explains the dorms and the cafeteria where Mizuki spits out her milk at this campus; it also identifies the roof of Building 3 for Sano and Dr. Umeda’s episode-2 conversation.

The campus is still an active university at Hirahata 120 in Ryugasaki. RKU says its Ryugasaki campus has operated since 1965 and currently opens specific facilities and events to the community, including general use of the student cafeteria and, for Ryugasaki residents, the library under its rules. This coordinate is a campus-level pin, not a claim about the exact 2007 cafeteria table, gym position, or rooftop camera mark. Visitors should use only areas currently open to the public and should not enter classrooms, rooftops, or student-only spaces for filming-location photos.
