J-Drama Pilgrimage | 安堂ロイド Ando Lloyd (2013) — 横浜市大倉山記念館 / Tokyo Imperial University

Episode 3 of TBS’s 『安堂ロイド～A.I. knows LOVE？～』 aired on October 27, 2013. The Nationwide Filming Location Guide identifies 横浜市大倉山記念館 / Yokohama Okurayama Memorial Hall as one of the real locations used for the fictional 東京帝國大学, including the sequence around 七瀬 / Nanase and the later confrontation involving Lloyd and detective Ashimo.

TBS’s official episode-3 synopsis says Asahi rushes to Tokyo Imperial University after realizing Lloyd has gone there to eliminate Nanase. The location guide separately identifies Seikei University for the fictional university’s main gate, so this memory does not collapse the drama’s composite campus into a single real site.

Okurayama Memorial Hall remains an active Yokohama civic cultural facility at 2-10-1 Okurayama, Kohoku-ku, inside Okurayama Park. The 1932 building is a Yokohama-designated tangible cultural property and is still used for concerts, exhibitions, meetings, and filming. Common areas may be visitable, but booked rooms should not be entered without permission. The pin marks the building, not a specific 2013 room, actor position, or camera setup.
