Japanese Building & Room Kanji: 家 (House), 室 (Room), 屋 (Shop/Roof), 店 (Store) & 院 (Institution)

Look closely at 室 (Room — shitsu) and 屋 (Shop/Roof — ya): both have the exact same inner component 至 (Arrive at Earth 土)! The only difference is whether it sits under a symmetrical house roof (宀 → 室, as in 教室 kyōshitsu 'classroom') or a slanted shop awning (尸 → 屋, as in 部屋 heya 'room' and 本屋 hon'ya 'bookstore')!
