Editorial: Deeper debate urged on separate surnames, same-sex marriage in Japan election
In the upcoming House of Councillors election, the introduction of a selective married couple surname system and the legalization of same-sex marriage have again emerged as key issues.
In the recently closed session of the Diet, legislation to introduce selective separate surnames was deliberated in the House of Representatives for the first time in 28 years. However, parties that had advocated for the change were unable to unite, resulting in a decision to carry the discussion into the next session.
Under the current system that requires married couples to share a surname, nearly all of those who suffer disadvantages from a name change are women. Premarriage career achievements can go unrecognized by society. Some women also report a sense of lost identity.
The Constitutional Democratic Party of Japan (CDP) and the Democratic Party for the People, both of whom submitted their respective bills, have again pledged to introduce the system in their campaign promises. The ruling Liberal Democratic Party (LDP), where members are split on the issue, has yet to present a clear direction.
The LDP's conservative bloc and the Sanseito party oppose the reform. Critics claim that allowing separate surnames would leave children with a different last name from one parent, undermining family unity and negatively affecting child development.
However, these concerns have not surfaced in countries where separate surnames are allowed. In Japan as well, there are a number of families -- such as those in common-law marriages -- where members do not share the same surname.
Safeguarding the rights of same-sex couples is also an urgent issue. In lawsuits filed by affected individuals, all five high courts that have rendered judgments so far have found the current system, which fails to recognize same-sex marriage, to be unconstitutional.
Even though sexual orientation cannot be changed, unequal treatment persists. Such discrimination is unreasonable, and it harms people's dignity while causing everyday difficulties.
Some continue to deny same-sex marriage, citing the traditional view that marriage is for "a man and a woman to live together and bear and raise children." However, the ability or intention to have children is not a legal requirement for marriage in Japan.
The CDP, Nippon Ishin (the Japan Innovation Party), the Japanese Communist Party and others have pledged to make same-sex marriage legal, but the LDP's manifesto does not address the issue.
The introduction of selective married couple surnames and same-sex marriage would grant the wishes of those who desire them without disadvantaging anyone else.
The Constitution stipulates that the right of the people to pursue happiness must be fully respected in national policy. Voters should scrutinize how candidates and political parties intend to put this principle into practice.

46% in Japan have low expectations for controversial Sanseito party: Mainichi poll
TOKYO -- Nearly half of people in Japan expect little from Sanseito, the populist party that made significant gains in the latest House of Councillors election, according to a nationwide Mainichi Shimbun survey conducted June 26 and 27. Forty-six percent of respondents did not consider the party to be promising, far more than the 19% who said they had expectations for it. Meanwhile, 34% replied "not sure." Sanseito ran in the upper house election on a "Japanese First" platform, increasing its seats from one to 14 among those up for grabs this time. While it appears to have served as an outlet for dissatisfaction with the ruling coalition, the party has also drawn criticism. For example, a newly elected candidate controversially said, "Nuclear armament is the cheapest policy," when discussing national security. The survey was conducted using the smartphone-based "d-Survey" method. NTT Docomo's "d Point Club" member base, covering about 74 million people ages 18 and up nationwide, was used to randomly select respondents. The poll received 2,045 valid responses.

Japan ruling party eyes plenary meeting amid rift over PM resignation
TOKYO - Japan's ruling Liberal Democratic Party decided Tuesday to hold a plenary meeting of its parliamentary members soon, as Prime Minister Shigeru Ishiba insists on remaining in office despite calls from among his party to step down following a devastating national election loss. The joint plenary meeting of members of both houses of the Diet is one of the LDP's decision-making bodies. A similar gathering was held on Monday in a less formal setting where many members called on Ishiba, the LDP president, to step down. The upcoming gathering could put further pressure on Ishiba, who has stressed the need to avoid a political vacuum at a time when the nation is facing a host of challenges, including the imposition of U.S. tariffs on Japanese imports. "It all comes down to explaining myself carefully, sincerely and without running away," Ishiba said. LDP Secretary General Hiroshi Moriyama told reporters that details, such as the date and agenda of the meeting, have yet to be set. Asked whether a joint plenary meeting has the authority to call for a snap party leadership election, Moriyama said it would involve a "very complex" process. The gathering is designated as a forum to discuss and decide in a majority vote on "particularly important" matters regarding the party's management and Diet affairs, according to the party's rules. In an emergency situation, such as when the head of the LDP resigns during a presidential term, a joint plenary meeting can elect a new party chief, substituting for a party convention. Although the ruling bloc no longer holds a majority in either chamber of parliament, a newly elected LDP president would still have a chance of becoming prime minister as the party and its smaller coalition partner Komeito are the largest force in the more powerful House of Representatives. Some LDP members have been collecting signatures to urge the leadership to hold a formal plenary meeting in their bid to hold Ishiba accountable. On Monday, LDP lawmakers from both houses of parliament held a meeting with party executives to discuss the outcome of the recent election and vent their feelings toward the leadership. It lasted well over four hours. The LDP's internal wrangling is expected to continue at a busy time for the government. An extraordinary Diet session will begin on Friday to select the upper house's new president following the July 20 election, which resulted in the LDP-Komeito bloc losing its majority and smaller opposition parties, including rightwing populist party Sanseito, increasing their presence. Ishiba is scheduled to explain to parliament the details of a trade agreement recently reached between Japan and the United States. The Japanese prime minister will also attend ceremonies to mark the U.S. atomic bombings of Hiroshima and Nagasaki as well as the end of World War II. By the end of August, the LDP is set to complete an internal review of the upper house election setback. Moriyama, the party's No.2 executive, has hinted at stepping down after the review.

Japan to deploy long-range anti-ship missiles in Kumamoto
A transporter and launch vehicle for the enhanced Type 12 anti-ship missile is seen at the Higashi-Fuji training area, Shizuoka Prefecture, on June 8. (Asahi Shimbun file photo) The Defense Ministry is finalizing a plan to deploy long‑range anti-ship missiles at a site in Kumamoto Prefecture as a deterrence to China, several government sources said. The domestically produced Type 12 missiles will be installed at the Ground Self-Defense Force's Camp Kengun in Kumamoto Prefecture during this fiscal year, at a time of stepped-up Chinese military maneuvers around the Nansei islands, the sources said. Japan's fiscal year runs through March 31. The government plans to operate the upgraded version of the Type 12 surface-to-ship missiles as a standoff capability, operating outside the enemy's range. The enhanced Type 12 missile has a range of 1,000 kilometers, greater than its predecessor. It can reach China's coastline. Government sources said the missile will be deployed to GSDF Camp Yufuin in the future, although the date has not been decided. It could come next fiscal year or later. Deployment to the GSDF's Vice Camp Katsuren in Okinawa Prefecture is also under consideration. Mass production of the upgraded Type 12 missile began in fiscal 2023. The weapon was test-fired last year on Niijima island south of Tokyo. The government named a standoff missile capability in its three revised security-related documents in 2022. However, the possession of these missiles has raised concerns from some quarters. One concern is that it increases the likelihood of the bases being targeted during hostilities. Another concern is that possessing standoff missiles is in conflict with Japan's Constitution, which limits the Self-Defense Forces to protecting the country.
