A survey conducted by Jiji Press shows 58% say Japan should join the TPP negotiations, with 22% against. (I know, 58+22 = 80 … it doesn’t say what the other 20% think :-))
The article provides further breakdown by political party affiliation.
Its interesting the hear of such poll results ahead of Abe’s visit to Obama in Washington, where the TPP talks are expected to play a big part in discussions. Recent press has highlighted strong internal opposition to the TPP within the LDP.
