The children can have a merry time here. We can see many families who sit in the grass and have a lunch box together. Sometimes some people take a nap comfortably in the shade of a tree. There are all kinds of flowers and trees in that place. So there is fragrant with the smell of flowers. There are filled with throngs of people on weekends. We can borrow a bicycle there, so we can see some couples who ride a bicycle together. There is held a composition competition for children sometimes. Where is this place?
