<h2> We have deviated from the guidelines.</h2>
 A battle of the sexes has broken out.
 On November 26, Sohei Kamiya, 48, the representative of the Sangen-tei, held a press conference in the Diet and announced that he had removed Mizuho Umemura, 47, a member of the House of Councilors, from the board of directors (decision-making body).
<div data-friday-ad-slot="AD_inArticle"></div>
 The reason was a weekly magazine report on Mayuko Toyoda, 51, an assistant to policy chief Mayuko Toyoda, who is also a member of the board.
 According to a November 25 report in Bunshun Online, when Toyoda approached the party to ask for an office space for herself, Umemura suggested that she use a party room on the second basement floor of the House of Councilors building.
 He was reportedly furious, saying, &#8220;You can&#8217;t keep me in the basement!
 Mr. Umemura was reportedly furious. Umemura told Bunshun, &#8220;Maybe I didn&#8217;t like the image of the basement.
 Maybe I didn&#8217;t like the image of the basement.
 Mr. Umemura responded to Bunshun, &#8220;Maybe I didn&#8217;t like the image of the basement.
 Speaking of Mr. Toyoda, eight years ago, he was accused of harassing his secretary by saying, &#8220;You son of a bitch!
 I&#8217;m so sorry!&#8221; and other such epithets.
 and other such abusive comments caused a major uproar. The media was very excited to see Mr. Toyoda&#8217;s passionate behavior, which foreshadowed his &#8220;resurrection&#8221; (see &#8230;&#8230;).
 Kamiya imposed the punishment on Umemura, not Toyoda. At the press conference, Kamiya said
 &#8220;We have dismissed board member Mizuho Umemura. As for the reason, we had warned her to manage information within the party properly, but she did not act in accordance with our guidelines.&#8221;
 He explained, &#8220;I had warned her to manage information within the party properly, but she did not act according to the guidelines. Under the party&#8217;s bylaws, it is forbidden to give interviews to the media on one&#8217;s own initiative. Mr. Kamiya then continued, &#8220;I don&#8217;t intend to look for the culprit.

 I don&#8217;t intend to look for the culprit, but I told them that we had to prevent rumors from spreading, and I think the problem lies in the fact that they didn&#8217;t follow my instructions.&#8221;
 Mr. Umemura, the party involved, in X
 It is very unworthy of me to have responded as an individual to an interview with a weekly magazine and deviated from the guidelines, and it pains me to think of the worry I must have caused to my fellow party members and all those who have always supported me so kindly and warmly.
 He also apologized for the trouble he had caused to his friends and colleagues.

<h2>Intense infighting three years ago when a national political party was born</h2>
 Although the Sangen-tei won seven seats in the recent Upper House election, a look back at the past reveals a history of &#8220;infighting.
 After the Upper House election three years ago, conflicts surfaced among Kamiya, Manabu Matsuda, Yumi Akao, Toshiaki Yoshino, and Kunihiko Takeda, all of whom contributed to the creation of a national political party. A war of criticism developed among party members, and the position of representative was transferred from Mr. Matsuda to Mr. Kamiya, while Mr. Akao, Mr. Yoshino, and Mr. Takeda were effectively expelled.

 When we spoke to a person in Nagata-cho who knows the Sangendō party, he said, &#8220;The uproar triggered the party&#8217;s formation,
 They said, &#8220;The uproar led to the concentration of power in Kamiya&#8217;s hands in order to prevent a party takeover or coup d&#8217;etat. Mr. Kamiya is the only one who can make decisions. The party is on the upswing, but there is some suspicion that some members may be acting strangely,&#8221; he said.
 Kamiya said, &#8220;The councilors are in high spirits, but there is some suspicion that some members are making strange moves.
 What alarmed Kamiya this time was the fact that information known only to a limited number of people was leaked to the outside world.
 Mr. Kamiya said, &#8220;It happened between Mr. Umemura and Mr. Toyoda. Frankly speaking, it is Mr. Umemura who is under suspicion. Mr. Toyoda became a member of the board of the Sangen-tei in September, but from the beginning there were fears that he would not get along with (Mr. Umemura).
 Ms. Toyoda is a super-elite, having graduated from the University of Tokyo&#8217;s Faculty of Law and then Harvard University, before going on to work for the Financial Services Agency and then the House of Representatives. According to a media source who knows her.
 &#8220;I admit that he is smart, but he puts that into every part of our conversations. No matter how much she tries to hide it, she exudes an aura of &#8216;I am different from you guys.
 She is not like them.
 Umemura, on the other hand, entered politics in 1919 after graduating from Ritsumeikan University, working for the travel agency JTB, and working as a TV personality. He has been controversial for his outspoken opinions.
<div data-friday-ad-slot="AD_inArticle"></div>
 Mr. Umemura is popular among party members, but he tends to go it alone. He and Mr. Toyoda would never get along. This time, Mr. Umemura, who feels indebted to Mr. Kamiya for picking him up after he quit the Restoration Party, took a mature step back, but I doubt that this will improve the relationship between the two.
 (A Nagatacho official) Regarding the current turmoil, political commentator Harumi Arima told this website, &#8220;Toyoda had a lot to deal with when he was in the Liberal Democratic Party,
 I thought Mr. Kamiya took a bold step in bringing in Mr. Toyoda, who had been through a lot when he was in the LDP. As the party grew, he probably needed her to help him build his policy theories. In fact, she has been useful, such as having Mr. Toyoda appear on NHK&#8217;s &#8220;Sunday Debate. As for Mr. Toyoda, he is probably looking for a chance to become a member of the council while doing menial work as a policy director. However, if the Sangen-joken party enforces the rule that &#8220;it is forbidden to give interviews to the mass media on one&#8217;s own initiative&#8221; as a result of the current turmoil, he will not be able to speak freely with the mass media. At a time when the party needs to expand its influence through an all-hands-on-deck approach, the loss of exposure to the mass media could cause the party to lose momentum.
 Kamiya said.
 Kamiya likened Umemura&#8217;s punishment to a legendary story of &#8220;crying and slashing the back of a horse. The Sangseito is a party that is flying by the seat of power, but the members of the party are all full of individuality, and Mr. Kamiya seems to have a hard time keeping up with them.

 The battle of the onnagata has broken out. On November 26, Sohei Kamiya, 48, the representative of the Sangen-tei Party, held a press conference in the Diet and announced that Mizuho Umemura, 47, a member of the House of Councilors, had been removed as a board member (decision-making body).
