<h2> &#8216;The anger I&#8217;ve been suppressing for so long.&#8221;</h2>
Yuto Oshiro (24 at the time of arrest), the representative of a construction company, and his acquaintance and accomplice Kaito Oshiro (25), were charged with robbery and confinement resulting in injury after detaining and assaulting a male business partner, causing him harm. Their trial was held at the Tokyo District Court on November 27.
During the defendants’ questioning that day, both expressed words of remorse, but the process by which their warped sense of justice escalated became clear.
“In January of this year, Yuto Oshiro, together with Kaito Oshiro and several other friends, conspired and broke into the home of a man they were in dispute with. They assaulted him, shaved his head with clippers, and stole approximately 850,000 yen in cash, gift certificates, and nine luxury watches—totaling around 3.2 million yen. Afterward, they forced the man into a car and abducted him to a nearby lodging facility. For about three months until the end of April, they moved him between more than a dozen locations while subjecting him to assaults, such as pressing a heated frying pan against him and pouring hot water over him, causing second-degree burns covering 10% of his body (damage extending beyond the skin to the dermis),” said a judicial reporter from a national newspaper.
On October 20, the defendants’ first trial was held. Details of this trial were reported in Friday Digital on October 25.

The defendants paid the victim 14.7 million yen in settlement money, but the man was left with lasting effects, including blurred vision in his right eye, as well as psychological scars that may never heal.
During questioning, Yuto Oshiro said about the incident:
“I inflicted terrible violence, and the endless fear must have been terrifying. What I did cannot be undone, but I do feel remorse.”
The trouble began over unpaid construction costs. The victim’s supervisor, Mr. A, refused to pay 700,000 yen for a wallpapering job performed by Yuto Oshiro’s construction company, citing defects. Yuto Oshiro said:
“I thought it was wrong not to receive proper compensation.”
He consulted with Kaito Oshiro and others and planned to collect the payment. During discussions with the victim, he admitted:
“All the anger I had been holding in became uncontrollable.”
He assaulted the man and ultimately succeeded in collecting the 700,000 yen. Furthermore, after learning that other construction companies had experienced “fraud” (according to Yuto Oshiro) similar to his own, he decided:
“I wanted to make other victims also pay their fair dues (through this man),”
and thus began the victim’s period of confinement.

When asked by his defense attorney, “When did you intend to release him?” Yuto Oshiro replied:
“I planned to release him once his treatment was finished and he had paid the outstanding amounts owed to other companies.”
Regarding the severe violence, he described:
“I couldn’t forgive him when we were together. I couldn’t accept bringing something black into a clean arena.”
When the prosecution questioned him about his motive, he claimed:
“People who had suffered similar harm and were struggling said, ‘Please help us,’ so I wanted to help them.”
The prosecution asked, “Before the trial started, you were smirking while making eye contact with Kaito Oshiro, weren’t you? How could you do that?” Yuto Oshiro quickly denied, saying, “I did not.” When the prosecution pressed further, asking, “You made eye contact, didn’t you?” he responded firmly, “I did not.”
Next, Kaito Oshiro took the stand.
“I thought I had to help my friend because he was in trouble. During our discussions, I just wanted Yuto to get his money back,” he explained as the reason for their conspiracy.
Regarding why he continued to detain the victim, he said:
“I was afraid of revenge from Mr. A if we released him, so I decided to do it. My anger switched on, and I thought I had to make sure he could never do that again,” escalating the violence.
As a result, Kaito Oshiro, like Yuto, let his warped sense of justice spiral out of control. He also learned about others who had suffered “fraud” from Mr. A’s company and reflected:
“I thought that people who do bad things deserve to have bad things done to them.”
However, following their arrest, his thinking changed:
“I now believe that solving problems with violence is wrong. I caused lifelong injuries, and I want to spend my life making amends,” showing remorse.
Regarding his relationship with Yuto Oshiro, he said:
“I will cut off my previous friendships and build new relationships,” pledging to end ties with Yuto.
The next trial session is scheduled for December 19, continuing with questioning of Kaito Oshiro. The prosecution is expected to pose more tough questions.
