What It Is

jump one is a Japanese offline fitness brand operated by LAVA International, Inc. It positions itself as "暗闇トランポリンフィットネス", meaning group trampoline training conducted under dim lighting, accompanied by music and led by an instructor. Per the brand's website, it emphasizes an experience of fat burning, body shaping, stress relief, and emotional renewal through jumping, dancing, and a group atmosphere.

Core Features

Its core offering is a 45-minute trampoline class, with the brand claiming a single session burns approximately 450-800kcal. Users can book trial classes online, select a studio location, check the class schedule, and manage or cancel bookings on their member page. Studios also provide amenities including towels, water, apparel rental, and non-slip socks, lowering the barrier for first-time visitors. Beyond the workout itself, the selling points of its classes include the dim environment, loud music, light shows, and the sense of collective participation.

Pricing

Pricing is disclosed fully. A trial class costs 3,300 JPY when paid by credit card via the website, or 3,850 JPY when paid in-store. Monthly membership plans include options for 30 classes, 11 classes, 4 classes, and weekday-only access, with core pricing ranging from 14,080-18,480 JPY per month, plus an additional 580 JPY monthly administrative fee. Single walk-in classes cost 4,400 JPY when paid by credit card online, or 4,950 JPY when paid in-store. Joining also requires an initiation fee, registration fee, facility usage fee, and membership card fee, making the first-time cost relatively high.

Pros & Cons

Pros: It has a distinct product concept, perfect for people tired of traditional gym machine workouts; trampoline training combines cardio, core stability, and balance training, with relatively low impact on joints. Operated by a large fitness group, it has mature studio management, a booking system, and standardized classes. Cons: It has a high price barrier with multiple fees in its membership structure; class availability, studio locations, and scheduling can limit how often you use it; additionally, the Japanese-only service environment may not be friendly to tourists or foreign users.

Who It's For

It is suitable for people residing long-term in Japan: office workers, female fitness enthusiasts, and those looking to lose fat and get in shape who want to stick to an exercise routine with high-energy group classes, as well as anyone who enjoys rhythm-and-music-focused workouts. It is not suitable for people who only want low-cost fitness, those who prefer free gym equipment training, or those who cannot commit to regular in-studio visits.

Access from China

The website itself can most likely be accessed directly from mainland China, but the service is entirely based at offline studios in Japan. Actual use requires you to be located in Japan to complete booking, payment, and attend classes in person.
