Opposition party-submitted resolutions rebuking Finance Minister Taro Aso for his refusal to receive a report questioning the ability of the country's pension system to meet retirees' needs were voted down in the Diet on Friday.
The House of Representatives rejected a no-confidence motion against Aso, who opposition parties argue made an "unprecedented" and "outrageous" move in rejecting a report on the basis that it does not give a true representation of the situation.
Aso, who also serves as minister for financial services and deputy prime minister, refused last week to receive the report, saying the panel's estimate contradicted the government's position that the pension system is able to meet "to some extent" people's household financial requirements in retirement.
