Chidorigafuchi National Cemetery, National cemetery and tomb of the unknown soldier in Sanbanchō, Tokyo, Japan

Chidorigafuchi National Cemetery is a secular memorial in Sanbanchō, Chiyoda, Tokyo, holding the unidentified remains of Second World War dead. Its grounds, designed by Yoshirō Taniguchi, centre on the hexagonal rokkakudō, an open pavilion with a low hipped roof on thick square pillars and a slatted screen on one side. Inside stands a five-tonne ceramic coffin containing a bronze urn given by Emperor Shōwa.

The Japanese government opened this site in 1959 after a special committee began collecting remains from former battle zones in 1952. The facility later expanded to accommodate a growing number of recovered remains that continued arriving from overseas locations.

The memorial is secular by design: its architect, Yoshirō Taniguchi, avoided any motif that could read as religious. Two stelae on the esplanade carry poems by Emperor Hirohito (March 1960) and his successor Akihito (September 2005). Each May the Ministry of Health, Labour and Welfare holds a commemorative service, and since 1959 religious and secular groups have held annual ceremonies here.

Visitors can reach the cemetery on foot from nearby subway stations and walk freely across the grounds without paying any entrance fee. The paths are paved and manageable even in wet weather, with the quietest hours usually falling in early morning or late afternoon.

Architect Yoshirō Taniguchi designed the layout and blended straightforward modernist lines with elements drawn from traditional Japanese memorial design. His approach shows in the clean geometry of the buildings and the open spaces that still convey a sense of restraint and respect.
