This park is a hidden treasure in Ogikubo. It has a modest traffic flow for such a lovely park. It is completely a Japanese traditional garden with stone bridges and a pond with koi and a wooden pavillion handing out over the water so you can observe the koi and the pond. This is a nice place to sit and read or write a letter. I see some elderly people bringing boxed lunches to the park to enjoy together, but be prepared to pack out what you bring in because there are no garbage cans (which has become the standard for all public places in Japan today). There is no fee to enter the park. This is a calm place where people go for peace. Screaming kids would be out of place here, but well behaved children would be very welcome.
