TOKYO (TR) – Last week, Tokyo Metropolitan Police arrested the founder of real estate investment company Raysum Co., Ltd. and two women over the alleged possession of illegal drugs in a luxury hotel room in Chiyoda Ward last year.
As previously reported, police found Tsuyoshi Tanaka, 60, to allegedly be in possession of approximately 0.859 grams of cocaine and approximately 0.208 grams of kakuseizai (methamphetamine) together with Miho Okumoto, 32, and Mona Konishi, 21, in a room of the hotel on June 24.
Police have not revealed whether the suspects admit to violating the Narcotics Control Act and the Stimulants Control Act.
To this point, few details have been revealed about actually transpired in that hotel room. However, news site News Post Seven provides details, much of which comes via the submission of a criminal complaint by Konishi, a student at the Institute of Science Tokyo, against Tanaka over alleged sexual assault.
A reporter for a national newspaper tells News Post Seven, 'Okumoto and Konishi were providing drug-fueled entertainment to Tanaka. However, when things got out of hand, Konishi asked her partner for help. The police rushed to the scene and discovered drugs in the room where the suspects were staying. This led to the arrests.'
On August 8, Konishi filed the criminal complaint, which complaint detailed the circumstances that led to how an ordinary female college student ended up getting caught up in a drug-fueled party. Tsuyoshi Tanaka, left, and Mona Konishi(X) Papakatsu
At the time, Konishi was 20 years old and a second-year student at the institute. Around February or March of last year, Konishi was approached by a scout on the streets of Roppongi. After providing him her contact information via the chat app Line, the scout began sending her 'job offers,' including hostess work and papakatsu , or compensated dating.
Regarding papakatsu, the scout explained that one offer for work at a hotel paid 200,000 yen an hour. The offer would involve one man and several women, who would touch each other in their underwear. She was assured that there would be no sexual intercourse with the man. The man would use drugs, but the women would not have to.
Attracted by the high pay, Konishi went to a specified luxury hotel in March. There, she first met Tanaka, the founder and former chairman of Raysum.
'When I arrived at the hotel, I found the defendant [Tanaka] and a young woman in her underwear,' the complaint reads. 'The accused instructed the complainant [me] to change into underwear, and [I] followed those instructions. As soon as [I] was in underwear, the [other] woman pretended to touch [my] breasts and genitals.
Tanaka took drugs as this transpired.
'At that time, [I] realized that there were several types of drugs, but did not know what kind of drugs they were other than marijuana, which had a strong smell,' the complaint continues. 'Large amount of money'
Despite being told that they did not need to use drugs, they were forced to put marijuana in their mouths, which caused them discomfort. They stayed at the hotel for 15 hours and then left. About three weeks later, Konishi received 3 million yen through the scout.
After that, between April and May, the scout called her twice. Konishi said, 'I decided to answer the call because I was being offered such a large amount of money.'
According to the complaint, the acts carried out on the second and third times were almost the same as the first. 'But there were multiple women accompanying [Tanaka], and sometimes more than three people, including [me], were present,' the complaint says.
It was during this time that Konishi learned that the man's name was Tanaka Tsuyoshi, and that the drugs other than marijuana were cocaine and stimulants.
On the third occasion, Konishi claims that she was forced to inhale drugs other than marijuana. While she was in a daze, Tanaka inserted a toy into her, causing her pain. Tokyo police arrested Miho Okumoto last week over the alleged possession of illegal drugs (X) 'In a daze from taking drugs'
Despite feeling uncomfortable, Konishi returned for a fourth visit on the evening of June 24, the day of the incident.
'Tanaka and Okumoto were in the room,' another news reporter says of the hotel room upon the arrival of Konishi. 'They were both already in a daze from taking drugs.'
Konishi's first impression of Tanaka was that 'he was a man who asked for strange things, but he was a gentle person and didn't seem scary.' However, Tanaka was different that day. He ordered Konishi, who had just arrived at the room, to get naked.
Okumoto then touched Konishi's breasts and genitals. Tanaka, who had only looked at Konishi up until then, reached out to touch her body. As they fondled her, both of the suspects had cream that appeared to contain drugs on their hands.
Konishi filed the complaint for non-consensual sexual intercourse resulting in injury, claiming that she had suffered post-traumatic stress disorder as a result of Tanaka forcing her to perform sexual acts.

After the incident, Tanaka entered a hospital in Chiba Prefecture. He founded the real estate investment company Raysum in 1992. Within nine years, it was listed on JASDAQ stock exchange.
Currently, Raysum is a wholly owned subsidiary of real estate company Hulic Co.,Ltd. Tanaka served as chairman of the board of directors of Raysum until November 2021.
Indeed, Tanaka was a luminary in the real estate business. But, according to Shukan Bunshun , he was also widely known for paying women for companionship.
A person connected to a bar in Minato Ward says Tanaka prefers young ladies from the ward. 'Tanaka paid high fees to male 'attendants' to prepare young women for him,' the source assures. 'He mainly targeted 'Minato Ward girls,' including hostesses, influencers and adult video actresses. He called multiple young women to a hotel and had them perform obscene acts under the guise of 'entertainment.' He was famous for papakatsu because he paid large amounts of money to women as compensation.'
Okumoto, a native of Kyoto Prefecture, fit the bill. Popular on Instagram, she moved to Tokyo and worked for a period at an advertising company. She then went on to other things.
'Okumoto had been an underground idol, a race queen and a gravure model,' an acquaintance of hers says. 'She had no permanent job. Recently, she had been working at a hostess club in Roppongi, but her work schedule was irregular and she was the type of person who just went with the flow. That's when she met Tanaka and got immersed in high-value projects. I heard she was a regular.'
