Japanese Prime Minister Shinzo Abe resigns

Shinzo Abe, Japan's longest-serving prime minister, says he's resigning because a chronic illness has resurfaced.

Concerns about Abe's health began this summer and grew this month when he visited a Tokyo hospital two weeks in a row for unspecified health checkups.

Abe has acknowledged having ulcerative colitis, an incurable inflammatory bowel disease, since he was a teenager, and has said the condition had been controlled with treatment.

Abe, whose term ends in September 2021, is expected to stay on until a new party leader is elected and formally approved by the parliament. 

Abe said, "It is gut wrenching to have to leave my job before accomplishing my goals."

In a country once known for its short-tenured prime ministers, the departure marks the end of an unusual era of stability that saw the Japanese leader strike up strong ties with President Donald Trump even as Abe's ultra-nationalism riled the Koreas and China.

While he pulled Japan out of recession, the economy has been battered anew by the coronavirus pandemic, and Abe has failed to achieve his cherished goal to formally rewrite the U.S.-drafted pacifist constitution because of poor public support.

Abe is a political blue blood who was groomed to follow in the footsteps of his grandfather, former Prime Minister Nobusuke Kishi. His political rhetoric often focused on making Japan a "normal" and "beautiful" nation with a stronger military and bigger role in international affairs.

Abe became Japan's youngest prime minister in 2006, at age 52, but his overly nationalistic first stint abruptly ended in disappointment a year later because of his health.

In December 2012, Abe returned to power, prioritizing economic measures over his nationalist agenda. He won six national elections and built a rock-solid grip on power, bolstering Japan's defense role and capability and its security alliance with the U.S. He also stepped up patriotic education at schools and raised Japan's international profile.

Abe on Monday became Japan's longest serving prime minister by consecutive days in office, eclipsing the record of Eisaku Sato, his great-uncle, who served 2,798 days from 1964 to 1972.

But his second hospital visit Monday has accelerated speculation and political maneuvering toward a post-Abe regime.

Ulcerative colitis causes inflammation and sometimes polyps in the bowels. People with the condition can have a normal life expectancy but serious cases can involve life-threatening complications.

After his recent hospital visits were reported, top officials from Abe's Cabinet and the ruling party said Abe was overworked and badly needed rest.

His health concerns added to speculation that Abe's days in office were numbered; his support ratings were already at their lowest levels due to his handling of the coronavirus pandemic and its severe impact on the economy, on top of a stream of political scandals.

There are a slew of politicians eager to replace Abe.

Shigeru Ishiba, a 63-year-old hawkish former defense minister and Abe's archrival, is a favorite next leader in media surveys, though he is less popular within the ruling party. A low-key former foreign minister, Fumio Kishida, Defense Minister Taro Kono, Chief Cabinet Secretary Yoshihide Suga, and economic revitalization minister Yasutoshi Nishimura, who is in charge of coronavirus measures, are widely speculated in Japanese media as potential successors.

Abe, who repeatedly faced public criticism for his handling of the coronavirus outbreak, was often upstaged by Tokyo Gov. Yuriko Koike, a former ruling party conservative who's seen as a potential prime minister candidate by some. But she would have to first be elected to parliament to be in the running for the top job.

The end of Abe's scandal-laden first stint as prime minister was the beginning of six years of annual leadership change, remembered as an era of "revolving door" politics that lacked stability and long-term policies.

When he returned to office in 2012, Abe vowed to revitalize the nation and get its economy out of its deflationary doldrums with his "Abenomics" formula, which combines fiscal stimulus, monetary easing and structural reforms.

Abe's unpopular coronavirus measures sent his support ratings plummeting before his health issues. 

Perhaps Abe's biggest failure was his inability to fulfill a long-cherished goal of his grandfather to formally rewrite the U.S.-drafted pacifist constitution. Abe and his ultra-conservative supporters see the U.S.-drafted constitution as a humiliating legacy of Japan's WWII defeat.

He was also unable to achieve his goal of settling several unfinished wartime legacies, including normalizing ties with North Korea, settling island disputes with neighbors and signing a peace treaty with Russia.
