Time Out says
Located in a sleepy residential area right in between Nishi-Ogikubo and Kamishakuji stations, this spacious city park features a pond with rowboat rentals, several clean and well-maintained playgrounds and a small Benzaiten shrine. Despite its natural beauty and convenient facilities, Zenpukuji is rarely crowded and is thus a nice place for escaping the hustle and bustle of the city. The only downside is that the park is somewhat hard to reach – taking a bus from either of the above-mentioned stations is probably your best bet.
