The proportion of Japanese who consider Prime Minister Fumio Kishida's response to rising prices to be inadequate came to 64.1%, while 28.1% said it is satisfactory, a survey showed Monday, just weeks ahead of a crucial Upper House election.

In a three-day nationwide telephone poll by Kyodo News conducted from Saturday, a total of 77.3% said rising prices of food and other daily necessities have affected their lives to a varying degree, up 8.6 percentage points from the April survey.

Ahead of the Upper House election expected to take place next month, 71.1% said they would take higher costs of living into consideration when voting.
