Burials in SIngapore are very rare these days. Lack of land has required many old cemteries to be exhumed and the remains claimed by relatives for cremation. There are a few exceptions. Bukit Brown Cemetery contains about 100,000 graves and is believed to be the largest Chinese cemetery outside of China. It is the burial location of many of Singapore's pioneers. The graves are usually overgrown but in April each year during Qingming, the grave sweeping festival, the graves are cleaned up and the grass cut. Then joss sticks and spirit money are burnt and you ask your ancestors for blessings. There are Malay Kubors dotted around as well. The most famous being the one on Jalan Kubor off Victoria Street in the Rochor district. Kubors can often be found on the edge of estates that were once villages. Usually in a nondescript grassy area between estates scattered among the coconut and fruit trees. The Japanese Cemetery is another exception that was started in 1891 and it is the largest Japanese cemetery in Southeast Asia, containing 910 tombstones. The cemetery servers as the final resting place for members of the Japanese community in Singapore, including civilians, soldiers, and individuals who were executed for war crimes at Changi Prison, as well as others who were involved in the wartime sex trade. The site was gazetted as a memorial park by the Singapore Government in 1987.
