<p> Shinichi Sato, 62, a former professor at the University of Tokyo Graduate School of Medicine, was arrested by the Tokyo Metropolitan Police Department on January 24 and charged with bribery on February 13. It is suspected that in exchange for favors in their joint research on the efficacy of marijuana ingredients, he received a total of nearly 5 million yen in entertainment at brothels and other places from the Japan Cosmetic Association, the research partner. Ayumi Yoshizaki, 46, a former specially-appointed associate professor who worked under Sato, was also referred to prosecutors on the same charge.</p>

<p> How did a well-known professor who served as the head of the dermatology department of a Tokyo University hospital turn into a &#8220;monster who begged for sexual entertainment? The author obtained a photo of Sato&#8217;s first &#8220;3-day/2-night business trip to Bangkok,&#8221; where he received sexual entertainment.</p>
<p> The message at the beginning of this article is a message from &#8220;Goudai Sato&#8221; to Koichi Hikichi, 52, the president of the association, after his return from a business trip to Bangkok, in which he expressed his gratitude to Yoshizaki for his hospitality. The trip was conducted in early March 2012 as part of a research project, and Sato and Yoshizaki were accompanied by a research partner from the association to inspect a marijuana plantation and other sites.</p>
<p> It was the first night of the trip. After dinner, the group entered a top-quality club in the center of Bangkok. They were taken to a huge VIP room equipped with a billiard table and bar counter. Hikichi recalls the experience.</p>
<p><span class="strongInContent"> There was a lineup of girls who looked like models, and we would pick one and have a drink with her. Both Sato and Yoshizaki were happily conversing in English. I think we were there for about three hours.</span></p>
<p> The club had a system that allowed them to take the women out to their accommodations. Until then, he had been entertaining women at clubs in Ginza and other places, but he might have been reluctant to do so when it came to &#8220;prostitution. Hikichi was concerned about this, so he asked Sato softly, &#8220;I heard that you can take the girls home with you. Sato immediately replied, &#8220;By all means! Sato immediately replied, &#8220;By all means!</p>
<p><span class="strongInContent"> He said it with such force that spit came flying. Sato negotiated with a woman who looked like the model Nanao, and Yoshizaki negotiated with a woman who looked like Miwako Kakei, and each received an OK. Then they instantly started fidgeting as if they wanted to leave early.</span></p>
<p> Hikichi said that the hotel room where he was staying was right next door to Sato&#8217;s. &#8220;We were working in the middle of the night, and I was working on the other side of the wall. While working in the middle of the night, he heard a woman&#8217;s glamorous voice coming from behind the wall.</p>
<div data-friday-ad-slot="AD_inArticle"></div>
<p> The next morning, Sato approached Hikichi and expressed her gratitude with a big smile.</p>
<p><span class="strongInContent"> I didn&#8217;t think I would ever be able to hold such a pretty woman,&#8221; he said. It was a fun night.</span></p>
<p> On the second day of the business trip, a female doctor from Japan joined the group, so the evening&#8217;s sake-fest was forsaken.</p>
<p><span class="strongInContent"> Since February &#8217;23, Sato and others have forced me to entertain them at high-class restaurants and clubs in Ginza. Given Sato&#8217;s power, I thought he would destroy our joint research, so I had no choice but to comply with his unreasonable demands. I knew he was a womanizer because he had his nose in Ginza, but I never expected it to go this far. &#8230;&#8230;&#8221; (Hikichi)</span></p>

<h2>No matter what he does, &#8220;sex life comes first.&#8221;</h2>
<p> His lower body, which had been ignited overnight, was no longer satisfied at the Ginza stores that did not involve skin contact, which is his area of expertise. At the first reception after returning to Japan, he was told, &#8220;The clubs are so expensive.</p>
<p><span class="strongInContent"> At the club, even if you pay that much money, you can&#8217;t even hold hands or kiss.</span></p>
<p> Since then, the after-party venue was changed from Ginza to a high-class soapland in Yoshiwara that charges 80,000 yen for 120 minutes. Sato&#8217;s begging escalated further. Hikichi says in an exasperated tone, &#8220;Sato asked me to have dinner with him.</p>
<p><span class="strongInContent"> Sato told me, &#8216;If you have dinner and then go to a sex club, your erection will be bad, so please reverse the schedule. After his wife discovered the HIV prevention supplement Sato was using and questioned him about it, she demanded that he &#8216;move the time in Yoshiwara up to around noon so as not to arouse suspicion.'&#8221;</span></p>
<div data-friday-ad-slot="AD_inArticle"></div>
<p> The extreme example was a request to rent a shower room at a company affiliated with the association before going to a brothel. It seems that Sato&#8217;s mysterious pride in wanting to show off his cleanliness to his regular bubbly girlfriends worked. He was forced to stop operations during that time, as employees were not allowed to enter.</p>
<p> Hikichi&#8217;s patience ran out at the end of the summer of 1949. It was at the end of the summer of 1949 that Hikichi&#8217;s patience ran out, when Sato threatened him at a dinner party. Hikichi filed a damage report with the police, and in May 2013, he filed a lawsuit against Sato and others, demanding about 42 million yen in damages. The complaint, which we have obtained, describes the manner in which he changed, saying, &#8220;I can close my course (joint research) tomorrow,&#8221; &#8220;I will eliminate you from society,&#8221; and &#8220;I was asked to bring 15 million yen if I did not want my course to be destroyed.</p>
<p> Hikichi concluded his tirade with the following words: &#8220;You didn&#8217;t pay me yourself.</p>
<p><span class="strongInContent"> He said, &#8220;I told them, &#8216;You didn&#8217;t pay me yourself, and all you do is demand things from me, using your authority as a shield. On top of that, my research was being destroyed and my debts increased, making my life a matter of life and death. Just thinking about it makes me angry.&#8221;</span></p>
<p> Is there any excuse for the abomination of a &#8220;charismatic professor&#8221; who is addicted to authority and sexual desire? (Some titles are omitted.)</p>

 It is probably fresh in your mind that a former professor of the Graduate School of Tokyo University has been arrested and indicted on bribery charges. This magazine independently obtained photos of "sexual entertainment on a business trip to Bangkok," which was the main cause of his arrest. We will now take a closer look at the whole story.

 Former professor of the Graduate School of Tokyo University was arrested and indicted on bribery charges after he was forced to "entertain at Yoshiwara soap operas", indulged in lavish entertainment with his research collaborators, and went on a bribery spree.
