On April 18, 2007, approximately four years after their marriage, Mr. Ono suddenly passed away due to liver failure. Ms. Wakamura sent handwritten faxes to various media outlets, expressing her feelings by writing, "It was so sudden, I cannot accept the reality."

Even amidst her profound sense of loss, she recalled her husband's words, "You have a role to play, so you mustn't quit your job," and decided to continue her acting career.

 

3. What are the infidelity allegations against Mayumi Wakamura?

The infidelity allegations against Ms. Wakamura date back to a 2001 trial. In a divorce lawsuit filed by the then-wife of actor Ken Watanabe, Ms. Wakamura's name came up as one of Watanabe's mistresses.

 

However, it is unclear whether the infidelity was recognized as a fact in court.

 

In the same trial, Kenjiro Ono, who would later become Wakamura's husband, testified that he had lent 450 million yen to Watanabe's then-wife, of which 41 million yen remains unpaid.

 

It is said that after this incident, Wakumura's work decreased significantly. However, she gradually began to appear in more period dramas and stage productions, and once again expanded her range of work as a talented actress.
