A licensed Ultraman Dyna yo-yo produced by Yutaka, a Japanese toy company, in 1997. The yo-yo was inspired by the Ultraman Dyna, a part of the larger Ultraman franchise that is iconic in Japanese tokusatsu (special effects) television.
The image of Ultraman Dyna, the titular hero of the series, is featured on its side caps, emphasizing the branding and tie-in with the series. A fixed axle yo-yo that used a cotton string. The response type is unknown. Likely either none or starburst. The shape is reminiscint of Jack Russell Coke yo-yos with the bulging side caps.
Ultraman Dyna aired on television in Japan from 1997 to 1998 as a follow-up to Ultraman Tiga. It follows the story of Shin Asuka, who transforms into Ultraman Dyna to battle monsters and aliens threatening Earth. The series was a huge success in Japan and remains a fan favorite in the Ultraman universe, which explains the wide range of merchandise produced, including this yo-yo.
