The Tokyo Nail Forum, sponsored by the Japan Nail Technician Association, was held in conjunction with Beauty World Japan from May 19th to 21st, with 88 companies and organizations exhibiting. Collaboration products were common at the venue. Shiny Gel, a collaboration with Sakura Cray-Pas, known for its familiar packaging featuring white doves and red roses, currently offers a lineup of over 70 colors. Even with the same color, viscosity varies depending on the pigment ratio, so some gel colors can be too viscous, prone to uneven application, and insufficient hardening. Sakura Cray-Pas' color-matching technology ensures that every color of gel maintains a consistent viscosity. Character products were also abundant, with Shineil currently offering a girly pink and black "Barbie" series. Not only the nail polish, but even the gel brushes are all in Barbie colors. Prigel announced the third installment of its collaboration series with Blythe Doll. This popular product features a doll selected to match the image of each color and printed on the packaging.

Other collaboration items include Disney, Sanrio, and Kumamon. While art requires skill, nail stickers are also available, so you can easily enjoy character nails.
