No.839 Entering with a march through "Nyujyomon"! Shirokane Elementary School sports day (Showa era)

In front of the gate with "nyujomon" (meaning "entrance fate") written in hiragana, and a pool was below it. The cover was closed during winter, but in summer they'd open the cover to make it a pool, while at other times it was used as a schoolyard. I often fell during races.
