Takaichi prepares a continuity cabinet and one seat for the Japan Innovation Party

Japanese Prime Minister Sanae Takaichi is preparing her first cabinet and Liberal Democratic Party shake-up since she took office last October, with a date as early as 16 September and a possible slip to 17 September, government sources told Jiji on 8 September. The headline change is not a purge. It is an invitation.

Takaichi plans to bring one minister from the Japan Innovation Party into the cabinet. The JIP has backed her government from outside since last autumn. The post on offer is internal affairs or regulatory reform. Names in circulation include former JIP leader Nobuyuki Baba, co-leader Fumitake Fujita and secretary-general Hiroshi Nakatsuka. The final choice, sources said, will follow the JIP’s own preference.

The rest of the sheet looks like continuity. Foreign Minister Toshimitsu Motegi, Defence Minister Shinjiro Koizumi and Finance Minister Satsuki Katayama are expected to stay. So are Chief Cabinet Secretary Minoru Kihara, LDP vice-president Taro Aso, who turns 86 on 20 September, and secretary-general Shunichi Suzuki, Aso’s brother-in-law. Policy chief Takayuki Kobayashi may keep his party job or move into a cabinet seat.

That cast is not an accident. Motegi and Katayama give her experienced hands for the autumn Diet and for a tax package that is supposed to include a consumption-tax cut on food. Koizumi lost the LDP presidency to Takaichi in a run-off last year. Leaving him at defence keeps a rival busy and keeps a familiar face at the ministry. Kihara is her closest ally in the Kantei. Aso remains the factional weight that helped make her president.

The calendar is tight. Okinawa elects a governor on 13 September. The cabinet is due to adopt the tax-reform outline in mid-September. Takaichi is expected in New York later in the month for the UN General Assembly. A reshuffle before New York lets her travel with a settled team. A reshuffle after Okinawa lets her avoid a personnel fight in the same news cycle as a prefectural loss or win.

JIP entry changes the coalition arithmetic more than the org chart. A party that has argued for regulatory cuts and a harder line on spending will own a ministry instead of shouting from the corridor. That is useful if Takaichi wants cover for the food-tax cut. It is also a concession. The LDP will give up one chair it has held alone since October.

Internal affairs is not a ceremonial seat. It oversees local government, broadcasting rules and parts of the digital brief. Regulatory reform is even closer to the JIP’s brand. Either job lets the junior partner claim a win at home in Osaka without touching foreign policy or the budget’s top line.

Takaichi’s own horizon is the 2027 LDP presidential race. A quiet reshuffle that keeps Koizumi, Motegi and Kobayashi inside the tent is a way to freeze the field for a year. A noisy one that dumps a rival would start the next campaign early. The leaks of 8 September are written to sound like the first option.

Nothing is signed until the night of the ceremony. Japanese personnel stories have a habit of shifting in the last 48 hours. What is already on the record is the design: keep the big three ministries, keep Aso’s circle, and give the JIP a chair. That is the government Takaichi wants to take to the autumn Diet and to New York.

The JIP’s price for walking inside the cabinet will show up in the autumn bills. If the new minister is given regulatory reform, expect a list of licences the party wants gone. If the post is internal affairs, expect a fight over local tax and broadcast rules. Takaichi can live with either fight. She cannot live with a junior partner that stays outside and votes against her tax cut after taking credit for putting her in office.
