TOKYO, Aug 17 (Reuters) - Japan raised its gasoline subsidy for oil distributors to 33.8 yen (25.2 cents) a litre for the seven days from Thursday, compared with 31.4 yen a week earlier, the industry ministry said on Wednesday.

The temporary subsidy programme was adopted in January to cushion a blow from high crude prices because of tight global supplies, while the Ukraine conflict that began on Feb. 24 added further pressure. ($1 = 134.1600 yen) (Reporting by Yuka Obayashi; Editing by Subhranshu Sahu)
