Safe and secure sandboxes
Among the 35+ anniversaries and observances in Japan on March 10th annually is Safe and Secure Sandbox Day 安全安心砂場の日 (Anzen Anshin Tsunaba no Hi). The anniversary was established by a company, HIsamitsu Center, that specializes in sandbox disinfection, playground equipment inspections and repairs for kindergartens, nursery cshools and childcare centers. The date comes from the wordplay on the date 3/10, which can be read as 'sand'—san (3) and do (10).
It begs the question; how often do other places get their sandboxes cleaned? Or do they? I wonder do they clean the sandboxes in parks regularly. With so many wild cats in Japan, cat poo in the sandbox is a real issue. There were a couple of times I spotted cat poo in a sandbox in a public playground. So I came to prefer the sandboxes that had netting around them. Apart from keeping cats out, they also keep children in!
The anniversary may have been established by a particular company with a particular service, but "Safe and Secure Sandbox Day" is a reminder that sandboxes in general are places we need to keep clean and safe for our children.

Former nickname was "Saitama". Changed it to save confusion on place review posts! Irish, 20+ years in Japan! I also write on my personal website: insaitama.com
