For some context, these subsidies did come to an end in May but were reinstated in August through to October to cope with the warmer weather. Subsequently, they were continued until this year-end but the funds had to be drawn from reserves in the budget for the fiscal year that started in April.
NHK is now reporting that the government is considering keeping these subsidies from January through to March next year. Amid a higher cost of living in key populated areas such as Tokyo, the measure above is mainly to try and combat rising consumer prices.
