The approval rating for Prime Minister Shinzo Abe's Cabinet has risen 6.1 percentage points to 72.8 percent, exceeding the 70 percent threshold for the first time since the failed Democratic Party of Japan administration was launched in September 2009, a survey showed Sunday.

The Cabinet's disapproval rating came to just 16.2 percent, according to its findings.

The poll, conducted over the weekend, also revealed that 63.0 percent of the respondents backed Japan's entry into the Trans-Pacific Partnership free-trade talks, a 10-point spike since the previous survey in January.
