[Makuake Launch] Eliminate summer back sweat with an "all-directional cooling system"! A next-generation model that blows air all the way to the head. Full-cover fan seat "Sokai" starts pre-sales today. Efficiently directs air conditioner's cool air to the back of the body.
Sankin Shoji Co., Ltd. has started pre-sales of the full-cover fan seat "Sokai" with an "all-directional cooling system" to eliminate summer back sweat, and the hybrid hot/cold seat "Onrei" from its car life brand SPEEDER on Makuake. This is the latest model in a series with a cumulative sales record of 7,000 units, offering efficient cooling and comfortable driving.

Sankin Shoji Co., Ltd. (Headquarters: Oita City, Oita Prefecture) officially commenced pre-sales of the full-cover fan seat "Sokai" and the hybrid hot/cold seat "Onrei" from the car life brand SPEEDER's latest project on the crowdfunding service "Makuake" starting today, Monday, April 27, 2026.
The model, boasting a cumulative sales record of 7,000 units (as of March 30, 2026, according to the implementer's research), has been fully renewed into an "all-directional cooling system" that allows air to penetrate from the buttocks and back all the way to the head. In addition to a dedicated ventilation model that eliminates severe summer stuffiness, a hybrid model with a built-in heater to cope with winter cold has also appeared. Pre-orders are now open with special discounted prices for early purchasers.
Makuake project is here
Reset the "driving stress" of midsummer. We want to eliminate the "unpleasant feeling in the buttocks and back" that strikes the moment you get in.
The moment you open the door, the hot air, and the moment you sit down, the unpleasant stuffiness that attacks your buttocks and back. SPEEDER fan seats were developed to solve this problem, which many drivers had given up on.
After many years of listening to customer feedback, we arrived at the "all-directional cooling system" that efficiently utilizes the cool air from the air conditioner. With scorching summers and rising fuel costs continuing, this smart heat countermeasure, which penetrates from the buttocks and back to the head, resets summer driving stress.
■ Overturning the conventional wisdom of "fan seats." The correct answer is "shortest distance direct delivery & all-directional" based on physics.
Many commercially available fan seats have pursued coolness by increasing the number and size of fans. However, the reality was that this came at the cost of creating new stresses such as "increased noise," "worsened seating comfort due to hardened seats," and "discomfort due to vibration."
What SPEEDER, which has continued to develop fan seats for many years, arrived at was not just brute force, but an "all-directional optimization" that efficiently cools from the buttocks to the head.
① SPEEDER's unique "low-intake" structure pursuing efficiency: Draws in cold air from the footwell where cold air accumulates and directly delivers it to the back and buttocks. Utilizing the laws of physics, this shortest route achieves an invigorating feeling the moment you sit down.
② "Surface-breathing" permeable structure: Instead of blowing air from localized points (ventilation holes), a new structure that circulates air throughout the entire seat has been adopted. This overcomes the conventional drawback where ventilation holes would be blocked by sitting, causing heat to build up. By allowing air to pass through the entire seat surface, heat emitted from the human body is efficiently dissipated, continuously eliminating uncomfortable stuffiness.
This is an image reproducing the airflow. It shows that a large amount of air blows out from the entire surface of the seat when the power is turned ON.
③ Linkage with double-head fans:
Efficiently cools the neck and makes driving safer. The area where air conditioner air reaches least is actually the driver's "head and neck." The neck contains thick blood vessels, and focusing on cooling this area is considered a very effective approach for efficient body temperature regulation and heatstroke prevention.
Full-cover fan seat "Sokai" combined with a headrest fan provides an invigorating feeling that envelops the whole body!
■ New structure for maintaining cleanliness. "3-part structure" allows the seat cover to be fully washable.
Sweat stains and odors accumulating on seats are unavoidable during summer drives. Many products have faced challenges with difficult maintenance, but SPEEDER has achieved complete separation with a "3-part structure" consisting of a "ventilation fan," "seat body," and "seat cover." When dirt is a concern, simply remove the fan and machine wash the seat cover. This allows you to maintain new-like cleanliness and comfort throughout the season.
■ Compact & low noise. A driving space that combines silence and comfort.
By uniquely reviewing the fan unit design, we achieved fan compactness and reduced noise. Compared to many commercially available products, powerful airflow capability is maintained while significantly reducing unpleasant operating noise. It provides ultimate coolness without disturbing conversations or music, even in the quiet interiors of hybrid cars and EVs.
■ Don't give up on coolness even during "idling stop" while parked.
In recent years, with the spread of idling stop, the problem of air conditioners stopping while parked has rapidly increased. This product supports power supply from your mobile battery by using a separately sold USB power cable. It can operate independently on battery power even when the car engine is off. You can maintain your own comfortable coolness regardless of location or situation, while saving on gasoline costs.
