The Japanese city official charged with administering the islands said yesterday he would like to have the controversial lighthouse removed by city workers. But he feared demonstrations from the right-wing groups that built it. Masatugu Oshima, general manager of the Ishigaki City General Affairs Department, said: 'If we could do this, it would be nice.' He said the row over sovereignty was jeopardising plans to start scheduled flights from Taiwan to boost the island chain's flagging tourist industry. But he was concerned right-wing groups 'could come and break our offices'. Mr Oshima said the group which had erected the structure were outsiders who had little support in the island group. 'They would cause trouble. In Ishigaki city we do not want this trouble.' Although officials rarely visit, a trip made after the lighthouse was built in July established there was no legitimate navigational reason for the structure. 'The light is too faint,' Mr Oshima said, adding that another beacon built on the disputed archipelago in 1978 was also useless.
