Case of CVR Approximately Tripled with AI Try-On. STAFF START's "Nakayoshi Mirror" Upgraded for Faster, More Accurate Results

VANISH STANDARD Co., Ltd. (Headquarters: Shibuya-ku, Tokyo; Representative Director: Noriaki Onozato) is pleased to announce the renewal of the generative engine (head-change engine) for its online try-on feature "Nakayoshi Mirror," offered within the "STAFF START" store staff DX service. This renewal enhances the natural synthesis of faces and hairstyles.

"Nakayoshi Mirror" is a feature that synthesizes consumer photos with staff styling images posted on STAFF START using AI, providing a try-on experience in just a few seconds, as if the user were wearing the staff's coordinated outfit.

Developed with the technical cooperation of SNAFTY Inc., a company specializing in service development utilizing generative AI technology, "Nakayoshi Mirror" began offering its services in 2025, boasting both speed and high quality in image generation. With this latest update, the image generation time has been further reduced, and the generation quality has been improved, enabling a speedier and more comfortable try-on experience on e-commerce sites. This aims to alleviate user concerns on e-commerce sites such as "I don't know if it suits me" or "It's hard to imagine how it would look when worn," providing a fulfilling customer experience that allows users to consider products more intuitively, enjoyably, and with greater confidence.

Update Highlights

1. Improved Head-Change Generation Speed This engine renewal has improved the generation speed of try-on images. Previously, it took approximately 20 seconds to complete generation, but after the update, generation is completed in approximately 8 seconds. This is a reduction of about 60% compared to before, allowing users to check styling that suits them more speedily. For users who want to try on multiple staff stylings simultaneously on an e-commerce site, the reduced waiting time allows for more comfortable comparison and consideration of numerous outfits. *Actual generation time may vary depending on network environment.

2. Enhanced Face and Hairstyle Reproduction Accuracy for a More "Like Me" Finish The new engine improves the reproduction accuracy during synthesis, including facial contours, impression of features, and how hairstyles blend. By reflecting the user's likeness more naturally than before, it is now possible to get a more realistic image of how the staff styling would look when worn by the user. The head-change, which includes hairstyles and contours, generates try-on images that are closer to the user's own atmosphere, going beyond simply swapping faces. The aim is to provide an experience on e-commerce sites similar to trying on clothes in a store while looking in a mirror, allowing users to intuitively check "Does it suit me?" or "Does it suit that person?"

Effect Case Example with Nakayoshi Mirror: CVR Approximately 3x Higher for Users Browsing Staff Coordinates

Among companies that have already introduced "Nakayoshi Mirror," some have seen users who utilized Nakayoshi Mirror (online try-on) achieve approximately 3 times the CVR compared to users who only browsed staff coordinates (Reporting period: June 2025 - May 2026). With this update, a smoother and more natural try-on experience can be provided than ever before. Users can try on desired staff stylings in a shorter time, and with the generated try-on images appearing more natural and closer to their own appearance, it leads to a customer experience that makes purchasing decisions easier, with further positive effects expected.
