TOKYO, May 18 (Reuters) - Japan raised its gasoline subsidy for oil distributors to 36.1 yen ($0.28) per litre for the seven days from May 19, up from 34.7 yen a week earlier, the industry ministry said on Wednesday.

The temporary subsidy programme was adopted in January to mitigate high fuel prices after tight global supplies boosted crude prices, with further pressure being added by the Ukraine conflict that began on Feb. 24.
