According to explosive reports released on Nov. 4 by Weekly bunshun AND FRIDAY29-year-old musician Wakai Koto was spotted spending the night with Nina (20), the youngest member of the popular 9-member girl group NiziU.
Media reports say the two were spotted entering Wakai’s apartment late at night, where Nina was allegedly staying. This report comes just months after Wakai’s previous dating scandal in March 2025, when he was photographed with gravure model Ichika Miri (26) – leading to speculation that the guitarist may have been romantically involved with both women at the same time.
The publications described the situation as a case of “simultaneous love”suggesting to double romance – a term that has quickly caught fire on social media platforms.
Following the reports, Japanese netizens took to X (formerly Twitter) to share their shock and amusement. Comments ranged from sarcastic to bewildered:
“Simultaneous love? Sounds like a new word for saying twice!”
“So he lives by the rock star cliché after all.”
While many expressed disappointment, others jokingly described Wakai as “the last true bandman left”, highlighting that Mrs. GREEN APPLE evolving towards a more refined, pop-oriented image, Wakai continues to “embody the wild spirit of a rock musician”.
Some fans have even suggested that if the rumors are true, it would only reaffirm Wakai’s identity as a “real rock star.”
When contacted for comment, Sony Music, NiziU’s management agency, acknowledged that Nina and Wakai had “bonded over their shared interest in guitar”, but firmly denied any romantic relationship, noting that they are merely “senior and junior colleagues”.
The agency also said that the rule of not dating NiziU does not apply to Nina, implying that even if the two were close, it would not constitute a violation of the group’s policy.
Neither Wakai nor its representatives have made personal statements regarding these reports.
While NiziU fans have expressed mixed feelings – some defend Nina’s privacy and maturity, others express concern for the group’s image – the majority agree that the young idol deserves respect amid widespread speculation.
“He’s 20 now and deserves to live his life” one fan wrote.
“As long as it doesn’t affect NiziU’s business, it’s fine.”
However, many are curious to know who Wakai’s “real girlfriend” is, as the musician has yet to clarify his relationship with Nina or Ichika Miri.
For now, both agencies have denied any romantic involvement, but the situation has attracted a lot of attention given the contrast between the two entertainers: the innocent and fresh-faced idol and the charismatic guitarist with a growing reputation for scandal.
Whether this is simply a misunderstanding between colleagues or a new celebrity romance in the making remains to be seen, but one thing is for sure: Wakai Koto’s “simultaneous love” rumor has become one of the most talked about entertainment stories in Japan this week.
