The Cabinet approved a plan Tuesday by the Imperial Household Agency to spend 190 million yen on funeral services and the construction of a tomb for Prince Takamado, who died last week.
The government will allocate 120 million yen in the current fiscal year from reserve funds set aside in this year's budget.
Although funeral services held by the Imperial household are religious rites, they are financed by the state treasury as members of the Imperial family hold public positions, the government said.
The Imperial Household Agency has earmarked 68 million yen for site preparations for the main funeral service, slated for Friday, and 30 million yen for ground preparations of the tomb construction.
Construction of the tomb itself, to begin next fiscal year, is expected to cost 67 million yen.
Prince Takamado, a first cousin to Emperor Akihito, died of heart failure Tuesday at age 47 after collapsing while playing squash with the Canadian ambassador at the Canadian Embassy in Tokyo.
The agency said the public will be allowed to pay their respects to Prince Takamado at Toshimagaoka Cemetery in Tokyo's Bunkyo Ward on Friday.
The Renso-no-gi Shinto funeral service will be held for the prince at the cemetery before he is cremated and interred in a tomb there.
The agency said people will have two chances to pay their respects -- between 11:40 a.m. and 12:30 p.m., and again between 1:30 and 2:30 p.m.
During the second session, the public can pay respects to a photograph of the prince as his body will have already been transported to the crematorium.
According to the agency, the public will also be allowed to visit his grave on Dec. 2 and 3 between 10 a.m. and 3 p.m.
