Sumire Matsubara Wins Lawsuit Against Ex-Boyfriend in “Muddy Court Battle,” Orders Return of 45 Million Yen Amid Internal Disputes

It has been revealed through our investigation that Sumire (34), the daughter of Junichi Ishida (70) and an actress, won 45 million yen in a lawsuit against her ex-boyfriend.

While her television appearances have decreased in recent years, Sumire married an ordinary man in November 2021 and gave birth to her first child in April 2022. It was believed that she was living a happy life in her private life.

However, it was reported by “NEWS Post Seven” (January 31, 2024) that there was a financial dispute with Mr. A, the man she dated from June 2018 to April 2021. The report detailed that Sumire had filed a lawsuit against Mr. A seeking the return of funds she had entrusted to him for investment.

On September 26, the Tokyo District Court issued a ruling ordering Mr. A to pay Sumire:

“The plaintiff (Sumire) is to receive 44,894,512 yen.”

What exactly was the nature of this financial dispute amounting to nearly 45 million yen?

 

“Let’s increase the amount through investment.”

Sumire began dating Mr. A around June 2018. As their relationship continued, A began to encourage Sumire to manage her assets. According to a statement submitted to the court by Sumire,

“I (Sumire) started to share my financial situation with A (note: referred to as the defendant in the statement). Then, about a year into our relationship, A told me, ‘It’s a waste to keep your money in the bank. You should invest it. I work in the financial world, so I’m knowledgeable about stocks and Bitcoin. I can manage your money well,’ and he said things like, ‘You need a financial advisor,’ leading me to entrust him with the investment of my assets.”

Thus, Sumire entrusted a total of 29 million yen to Mr. A, whom she considered an investment expert. He managed this money through various cryptocurrency transactions. During their dates, he would show her the account screens on his smartphone, saying things like, “It’s going well,” and “It’s rising.” From A’s comments, it seems that Sumire believed her assets were increasing smoothly.

However, in April 2021, the couple ended their relationship after nearly three years together.
