What It Is

4Y Plus is not design software in the traditional sense, but a creative performance and event support service for offline events. Its services center on street performances, stilt-walking parades, parent-child interactive programs, hands-on classes such as juggling/yo-yo/kendama, as well as event planning and back-office operational support. It is suitable for venues and scenarios such as shopping malls, schools, nursery schools, local festivals, theme parks, and more.

Core Capabilities

The official website presents its core services in three categories: performances, workshops, and event support. On the performance side, it offers shows by various performers, long-legged greeting acts, PomPom parent-child programs, and combined “Show + hands-on experience” packages. Workshops cover diabolo, juggling, yo-yo, kendama, stilt walking, and more, taught by active professional performers, and can be arranged for beginners or large-group experience sessions. For event support, it provides planning proposals, performer booking, stage production and choreography, schedule creation, rehearsal management, and on-site operation during the actual event.

Pricing and Terms

Pricing is quoted on a project basis. The website lists a reference performance fee starting from 50,000 yen, with the final amount consisting of the appearance fee, withholding tax, consumption tax, and actual travel/transportation expenses. Quotes can be requested for free. The cancellation policy is also relatively clear: 100% from the event day to 14 days prior, 50% from 15 to 30 days prior, and 20% earlier than that, though conditions may vary depending on the project.

Pros and Cons

Its main strength is a complete service chain: it can provide performer resources as well as on-site execution support. Its children’s and parent-child content is particularly strong, and programs can be adjusted based on age group, venue, and budget. Its publicly listed case studies cover large-scale events, theme parks, educational and welfare facilities, and media appearances, which adds credibility. The drawbacks are the lack of standardized package pricing and the need for Japanese-language communication for overseas clients. The service is highly dependent on offline execution, so costs and feasibility outside Japan are unclear.

Who It’s For and Access from China

4Y Plus is best suited to event organizers in Japan, schools/kindergartens, commercial facilities, parent-child activity organizations, and event teams that need professional street performances or interactive experiences. Access from mainland China cannot be determined from the crawled text alone, so it is marked as unknown.
