SANKIN SHOJI Co., Ltd. (Headquarters: Oita City, Oita Prefecture) began pre-sales of its full-cover fan seats "Sou-Kai" and "On-Rei" on the crowdfunding service "Makuake" for new and experimental products starting Monday, April 27, 2026. This project achieved 100% of its funding goal in just 4 hours after its public release. Since then, the momentum has not waned, and the voices of support continue to grow, with immense backing from many supporters. Our entire staff expresses our sincere gratitude. In response to the growing need for improved in-car environments due to recent extreme heat, the project is progressing smoothly towards delivery by the end of June.
Resetting the "driving stress" of midsummer. Eliminating the unpleasant sensation on your back and bottom that assaults you the moment you get in.
The moment you open the door, a wave of heat; the moment you sit down, an uncomfortable stuffiness attacks your back and bottom. To solve this problem, which many drivers had resigned themselves to, the SPEEDER fan seat was developed.
After many years of listening to customer feedback, we arrived at an "all-direction cooling system" that efficiently utilizes air conditioner cold air. With persistent heatwaves and rising fuel costs, this smart heat countermeasure, cooling from your bottom and back up to your head, resets summer driving stress.
■ Ranked high in Makuake rankings!
Thanks to significant support, we ranked in the TOP 10 in the outdoor category of Makuake's rankings.

■ Overturning the conventional wisdom of "fan seats." The correct answer is physics-based "shortest path direct delivery & all-direction."
Many conventional fan seats on the market have pursued coolness by increasing the number and size of fans. However, this often came at the cost of new stresses such as "increased noise," "hardened seats leading to poor sitting comfort," and "unpleasant vibrations."
SPEEDER, which has been developing fan seats for many years, has arrived at an "all-direction optimization" that efficiently cools from the bottom to the head, not just by brute force.
① SPEEDER's unique "low-intake" structure focused on efficiency: It draws in cool air accumulating at your feet and delivers it directly to your back and buttocks. Utilizing physical laws for the shortest route, it provides an instant refreshing sensation when seated.
② "Surface-breathing" permeable structure: Instead of blowing air from localized points (vents), a new structure is adopted that circulates air throughout the entire seat. This overcomes the conventional drawback where sitting would block vents and trap heat. By allowing air to pass through the entire seating surface, heat emitted from the body is efficiently dissipated, continuously eliminating uncomfortable stuffiness.
③ Linkage with double-head fans:
Efficiently cools the neck area for safer driving. The area where air conditioning is least likely to reach is actually the driver's "head and neck." The neck contains major blood vessels, and focusing on cooling this area is considered a very effective approach for efficient body temperature regulation and heatstroke prevention.
■ New structure for maintaining cleanliness. "3-part structure" allows for machine washing of seat covers.
In summer driving, sweat stains and odors accumulating on seats are unavoidable. Many products faced challenges with difficult maintenance, but SPEEDER achieved complete separation with a "3-part structure": "blower fan," "seat body," and "seat cover." If it gets dirty, simply remove the fan and machine wash the seat cover. You can maintain a constantly new-like cleanliness and comfort throughout the season.
■ Compact and low-noise. A driving space that combines silence and comfort.
By independently reviewing the fan unit design, we achieved fan compactness and low noise. Compared to common commercially available products, powerful airflow capacity is maintained while significantly reducing unpleasant operating noise. This provides supreme coolness without disturbing conversations or music, even in the quiet interiors of hybrid and EV cars.
■ Even when "idling stop" is active, don't give up on coolness.
In recent years, with the widespread adoption of idling stop, the problem of air conditioning stopping while stationary has rapidly increased. This product supports power supply from your mobile battery using a separately sold USB power cable. It can operate independently on battery even when the car engine is off. You can maintain your personal comfortable coolness regardless of location or situation, while saving on gasoline costs.
