TOKYO — One is a former prime minister known for his nationalistic views. A second is a hawkish former defense chief.
And a third is the son of Tokyo’s outspoken governor whose proposal to buy and develop a cluster of uninhabited islands claimed by both China and Japan has set off a territorial furor between the two countries.
That could ratchet up already tense relations with China and South Korea over territorial disputes that have flared in recent weeks and brought anti-Japanese demonstrations to dozens of Chinese cities.
There is little sign that Japanese have grown more nationalistic, but the ruling Democratic Party of Japan is expected to get clobbered in elections that Prime Minister Yoshihiko Noda says he will call soon.
Voters are angry with Mr. Noda’s push to double the sales tax and his party’s failure to bring promised change to Japan’s stodgy politics.
Polls suggest the Liberal Democrats will win the most seats in the more powerful lower house of parliament, although probably not the majority, so it would need to forge a governing coalition to rule.
If the Liberal Democrats regain power, its new leader, to be chosen in a Sept. 26 party vote, almost certainly would become the next prime minister.
The five candidates running for its top job, including former Prime Minister Shinzo Abe and former Defense Minister Shigeru Ishiba, have been taking turns calling on Japan to get tough with Beijing in the escalating dispute over the rocky outcroppings in the East China Sea called Senkaku in Japan and Diaoyu in China.
“Losing a piece of our territory eventually means losing the whole country,” declared Mr. Ishiba, a security and national defense specialist who is considered a hawk, at a news conference Wednesday.
He has said he would be in favor of developing the islands, a move that surely would anger China.
“Our beautiful countryside and ocean are under threat,” Mr. Abe, perhaps the most right-wing of the five, has said on the campaign trail.
