Evacuation plan from a single-storey nursery to the building next door
A single-storey nursery has no upstairs, so the plan is half about the building next door — and three people coming out to help halves the time the children spend outside

Notes in the source (in Japanese)
上が無い施設は、避難先を「作れない」。 借りる約束を先にしておくしかない。
平屋の保育園が、20m 先の 3 階建てへ避難する計画。園児 30 人のうち 15 人は抱っこ・おんぶが要る(0〜2 歳)。
受け入れ側が 3 人出ると、外にいる時間が半分になる ——これは園だけでは決められない数で、だから計画の半分は隣の建物の話になる。
浸水想定区域の保育所・学校・高齢者施設・病院などは、避難確保計画の作成と、計画で定めた訓練の実施と結果の報告が義務(水防法 15 条の 3 第 1・5 項)。対象は、市町村地域防災計画に名前が載った要配慮者利用施設(e-Gov 法令検索で条文を確認、2026-10-02)。
