Seat of the Roman Catholic Archdiocese of Tokyo. Designed by the famous architect Tange Kenzō, this ultramodern church was built in the 1960s to replace an older structure that was destroyed during the war.

Not one of the great gardens of Japan and sometimes a bit shabby, but a pleasant stroll with interesting trees, a medicinal herb garden and several ponds. Not to be confused with Koishikawa Korakuen.

A classical Japanese park with ponds, hills and teahouses, that was built in 1695 by Yanagisawa Yoshiyasu, a Tokugawa daimyo. It's a popular cherry blossom spot in spring and is lit up at night at this time.

The Toyo Bunko is a special library and a research institute of Oriental studies. The research focuses on Asian history and cultures. The Toyo Bunko collects and saves historical records of Asia. The collection of books exceeds 950,000 items. People can read the books free of charge. Library materials cannot leave the building. Photocopiers are available for use at a minimal charge.

Laid out in the 17th century, this splendid traditional garden boasts a large collection of trees and flowering plants that provide touches of beauty all year round. Winding paths, wooded hills, ponds teeming with ducks and fish. The place can be a little crowded at certain times of year (such as during the cherry blossom season in late March-mid April), but there's plenty of room for everyone.
