結婚できない男 Kekkon Dekinai Otoko (2006) | Yamani Securities — Kuwano’s Architectural Office Building

Yamani Securities in Nihombashi Kabutocho is the strongest surviving architectural anchor for Fuji TV/Kansai TV’s 2006『結婚できない男』. The filming-location archive identifies this building as Kuwano Shinsuke’s architectural design office, and also notes that the title sequence uses the building as Kuwano sits at a window looking upward.

Episode 4, broadcast on 25 July 2006, gives the location an especially memorable role: the rooftop stands in for the place where Kuwano watches the fireworks display. The same archive separates this building from the view supposedly seen from the office, which was filmed elsewhere, so this memory does not merge two different locations.

Yamani Securities still lists its head office at 4-1 Nihombashi Kabutocho, Chuo-ku. That makes the exterior a rare case where a major fictional workplace can still be matched to the same real-world corporate address twenty years later.

For pilgrimage, treat it as an active securities-office building rather than a tourist facility. View the exterior from ordinary public space and do not enter offices or attempt rooftop access. The stored pin is the current company/building-level position at 4-1 Kabutocho; it is not claimed as the exact 2006 window, rooftop mark, or camera position.
