Gasoline prices face many challenges, including the abolition of the temporary tax rate

As you may know, the government and opposition parties have been discussing the abolition of the provisional gasoline tax rate, which adds 25.1 yen per liter to the price of gasoline in recent years. If this were to be realized, it would be expected that prices would fall, but it is also true that the timing of this implementation is still unclear. Will the provisional tax rate really be abolished? If so, when will it be implemented? Future developments will be closely watched.
