who sued the creator of the otamatone over the king animatronic

I couldn’t verify a real lawsuit tying the Otamatone creator to a “King” animatronic from the available information, and the search result that surfaced appears to be a Reddit discussion rather than a primary legal source.

What I can confirm is that Otamatone was developed by CUBE Works and Maywa Denki, led by Masamichi and Nobumichi Tosa. The “King” lawsuit reference seems to be internet chatter, but I don’t have enough reliable evidence here to name a specific plaintiff or defendant with confidence.

What the result suggests

• The “creator of the Otamatone” points to Maywa Denki, not a widely reported lawsuit target.

• The “King animatronic” claim appears to be coming from a forum post, which is not strong enough on its own to identify who sued whom.

Most likely answer

At this point, the safest answer is: I can’t confirm that anyone did. The claim may be a misunderstanding, a meme, or a mix-up with another unrelated lawsuit.

Brief context

A separate entertainment lawsuit involving a “King” character has existed in the past, but that is not the same thing as a verified lawsuit against the Otamatone creator.

TL;DR: I can’t reliably name a person who sued the Otamatone creator over the King animatronic based on the sources available here.
