Sunday's sweeping victory by the Liberal Democratic Party-New Komeito ruling bloc in the Upper House election put an end to the divided Diet and hopefully to the "revolving door" of prime ministers over the past seven years, as ridiculed by foreign media.
That is at least until the next Lower House election, which must be held within the next three years.
But even though the ruling bloc secured a majority in the Upper House, the first time since the LDP's defeat in the 2007 election during Prime Minister Shinzo Abe's first stint at the nation's helm, he is not expected to rush into revising the pacifist Constitution, experts said, noting his priority will instead be boosting the fragile economy.
