The transport ministry said Friday it plans to drastically increase government subsidies for a new high-speed railway linking central Tokyo and Narita airport in its budgetary requests for the fiscal year starting next April.

The ministry wants the subsidy increased to 33 percent from the current 18 percent, ministry sources said.

The railway is to be primarily built by the Chiba Prefectural Government, various local governments and private companies. It will have total expenditures of 160 billion yen, they said.
