It has been four years since we moved from Tokyo to Tsu City, Mie Prefecture. When my children, who are now in middle and high school, were young in Tokyo, there were many places in the suburbs of Tokyo where they could play from morning to night to the point of exhaustion, and where they could play all day on a vast site. The advantage of moving to a community from the city center is that there are many spacious areas scattered throughout the city where children can play freely and spontaneously. Four years ago, when I first visited Nakasei Green Park, a 15-minute drive from my home, I was impressed by its vast grounds, ample playground equipment, and easy access to a place where children can play until they are exhausted.
