Our note
A data-driven architecture explainer that models a south-facing Tokyo room, plots the sun path, then fills 365 × 24 cells day by day to count sunny hours at a table: 656.3 hours at 1.5 m from the window; the author notes 26 minutes.

Opus 5.5｜建築のなぜ #2 東京の南向きの窓がある部屋で、テーブルの上の1点に、1年で何時間日が当たるか。 365日×24時間＝8,760マスを1日ずつ塗って数える映像を、Opus 5.5 に作らせました。 窓から1.5mで656.3時間。1m奥へ動かすと183.2時間、約3.6分の1になりました。
