I was surprised to hear that overnight talk was of polls showing the LDP cruising to victory with >50% of the seats and hence not having to form a coalition to govern. Surpised and incredulous. Here’s more info:

The main opposition party, headed by Shinzo Abe, and its ally, New Komeito, could together secure nearly 300 seats in the 480-seat House of Representatives, according to the telephone survey conducted over two days through Wednesday covering 123,700 eligible voters randomly selected across the country.
