Something that may be of interest: No. 2 on the PR winners' list was Yamada Toshio (also No. 2 in 2007).
Yamada is a former executive of JA’s peak body, the National Central Union of Agricultural Cooperatives, or JA-Zenchū. What is perhaps significant is the fact that he won just under 450,000 votes in the 2007 UH election and only just under 340,000 votes this time. That's a fall of around 25%. One could read into this a not insignificant decline in JA's organisational vote, considering that Yamada mobilises the vote of JA staff and their families around the country plus a few farmers. I do not think the decline would be due to the LDP's support for participating in the TPP negotiations in light of the fact that so many of its candidates won such thumping victories in 'rural' single-seat prefectural constituencies. PM Abe called JA's bluff on this one and won. What also struck me is how well the LDP has done across all constituency types, suggesting that its support base is increasingly well balanced across the urban-rural spectrum (even more so than in the Lower House election last December, which also showed evidence of the same phenomenon).

Best wishes,
