Japanese Politics Updates – June 28, 2026

Weekly Briefing Synopsis

Good morning, and welcome to the recap of the 281st episode of Japanese Politics One-on-One. It has been a wet and unsettled week. Two typhoons passed through in the same twenty-four-hour period, and Japan recorded nineteen earthquakes, several of them large enough to be felt in Tokyo. I spent the week on the good ship Gryms in Katsuyama, riding out the weather on the boat. We are now three weeks from the end of the current Diet session, and the prime minister is trying to close it out without leaving too many loose ends.

The Diet Endgame: Three Weeks and Eighteen Bills

When the session began in late January, sixty-three bills were on the agenda. Forty-five have passed; eighteen remain. The most politically sensitive are the two Prime Minister promised Ishin in exchange for their cooperation on an issue-by-issue basis. One would reduce the number of lower-house seats by forty-five. The LDP leadership supports it, but some LDP members are less enthusiastic. The other would designate Osaka as Japan’s secondary capital, a symbolic resilience measure. Both still need upper-house votes, and the opposition is in no hurry to help. There is also imperial succession legislation under discussion. Such measures would allow certain female members to remain in the household after marriage and that would permit the appointment of additional males from collateral lines. These questions are always delicate and cut across party lines.

The Smear Campaign and Mounting Pressure

The larger domestic story remains the rolling coverage in Bunshun of an alleged pre-leadership smear operation run by the prime minister’s staff against other LDP contenders. The prime minister spent Monday and Tuesday in budget committee sessions in both houses. On Friday she drew a line: she would no longer submit to live questioning and would instead allow her secretary to provide written testimony. The Constitutional Democratic Party has threatened to withhold cooperation on pending bills unless it receives more answers. Her approval rating has softened to around sixty-one percent, and she is visibly tired. The post-election honeymoon is over. At the same time, the LDP understands that the party’s lower-house majority is what matters most, and the prime minister is showing she can push back when pressed.

LDP Internal Currents: Aso, Suzuki and Obuchi

Taro Aso remains the pivotal figure. His early support helped put the prime minister in office, and his “We Love Takaichi” group was formed to signal unity. The relationship now looks more transactional. Last week Secretary-General Suzuki — Aso’s brother-in-law — publicly ruled out any extension of the current Diet session. That removed one of the prime minister’s potential safety valves. Yuko Obuchi’s resignation from the tax committee over the food consumption tax cut added another signal of internal unease. Obuchi, daughter of a former prime minister and herself a figure with leadership potential, said the measure was not fiscally responsible. Her departure is being watched carefully inside and outside the party.

Defense Posture and the Northern Shadow

On the security side, the Diet approved changing the name of the Air Self-Defense Force to the Space and Air Self-Defense Force. This is a formal step into the space domain that arrived with relatively little prior fanfare. The Global Combat Air Programme with the United Kingdom and Italy continues to attract interest. Canada’s defence minister expressed a desire to participate during a recent visit to Tokyo. North Korea, for its part, commissioned a new nuclear-powered missile destroyer last week, with senior Russian officials attending the ceremony, and announced plans to build two large surface combatants per year for the next five years. That development adds another layer to an already diversified North Korean nuclear deterrent at sea.

Economic Signals: Tax, Investment and the Yen

The consumption tax on food is to drop from eight percent to one percent. Furthermore, additional support for lower-income households. The prime minister continues to insist on fiscal discipline and has ruled out simply issuing more bonds to cover the shortfall. At the same time she has put forward a long-term strategic investment framework on the order of $2.3 trillion aimed at key technologies and industries. The yen closed the week at 161.7 to the dollar, now four weeks above the psychological 160 line. The Bank of Japan raised its policy rate at its most recent meeting. This highlights the tension between the government’s desire for fiscal room and the central bank’s normalisation path.

What Comes Next

The prime minister leaves Tuesday for a shortened visit to India for the annual summit. She will be back before the end of the week. With three weeks left on the constitutional clock, Monday and Tuesday will be important. She must manage the smear-campaign fallout while trying to keep the upper-house votes she needs for the Ishin-related bills. The opposition’s job is to keep throwing stones. The LDP’s job is to protect its majority without giving away too much ground. Summer will be when the real internal positioning begins.

Q&A

• Could Prime Minister Takaichi pursue something like a Nixon-to-China opening with North Korea, given the abductions issue and the regime’s hostility?
• Why have past large-scale investments in big Japanese companies produced disappointing results, and how will the new long-term strategy avoid repeating that pattern?
• Did Japan send earthquake rescue teams to Venezuela after the recent quake there?
• What did you make of the positive coverage of Japanese World Cup soccer fans in Texas, and does it represent a branding opportunity for the United States?
• What is your reading of Yuko Obuchi’s resignation from the tax committee?
• How does the prime minister justify not using additional government bonds to offset the revenue loss from the consumption tax cut on food?
