Naoshima is an island in the Japanese Seto Inland Sea that has pleasant cycling routes along the coast although it is hilly when you go inland. This sign translates as “Safe Traffic for Older People: Silver Road”. The old man looks quite jolly dancing with the little girl who is helping him cross the road. Possibly “silver” means he can get away with a few coins as a tip? In that case, he can invite her for a cup of sake rice wine afterwards. We are just suggesting this. She could also have a glass of lemonade. Could this actually be his wife?
