[Makuake Launch] Eliminate summer back sweat with an "Omnidirectional Cooling System"! A next-generation model with airflow reaching the head. Full Cover Fan Seat "Sokai" starts pre-sale today. Efficiently directs air conditioner cool air to the back of the body.

Sankin Shoji Co., Ltd. (Headquarters: Oita City, Oita Prefecture) officially commenced the pre-sale of its latest projects from the car-life brand SPEEDER, the Full Cover Fan Seat "Sokai" and the Hybrid Warm/Cool Seat "Onrei," on the crowdfunding service "Makuake" starting Monday, April 27, 2026.

The series, boasting cumulative sales of 7,000 units (as of March 30, 2026, according to the executor's research), has been fully renewed into an "Omnidirectional Cooling System" where air permeates from the buttocks and back up to the head. In addition to a dedicated air-blowing model that resolves severe stuffiness in summer, a hybrid model with built-in heaters for winter cold has also been introduced. Pre-orders for supporters at special discounted prices for early purchasers start today.

Resetting the "driving stress" of midsummer. Eliminating the "unpleasant sensation on the buttocks and back" that strikes the moment you get in.

The stuffiness that assaults your buttocks and back the moment you sit down, the intense heat when you open the car door. The SPEEDER fan seat was developed to solve this problem, which many drivers had resigned themselves to.

What we arrived at after many years of listening to customer feedback is the "Omnidirectional Cooling System" that efficiently utilizes the cool air from the air conditioner. With sweltering summers and rising fuel costs continuing, this smart heat countermeasure, which permeates from the buttocks and back up to the head, resets summer driving stress.

Overturning the conventional wisdom of "fan seats." The correct answer is "shortest direct route & omnidirectional" 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 new stresses such as "increased noise," "deterioration of seating comfort due to hardening of the seat," and "discomfort due to vibration."

What SPEEDER, which has been developing fan seats for many years, has arrived at is not merely brute force, but an "omnidirectional optimization" that efficiently cools from the buttocks to the head.

① SPEEDER's unique, efficiency-focused "low intake" structure: Cool air is drawn from the footwell, where it accumulates, and directly delivered to the back and buttocks. This shortens the route by leveraging the laws of physics, realizing instant refreshing comfort the moment you sit down.

② "Surface" breathing permeable structure: Instead of blowing air from localized points (ventilation holes), a new structure is adopted where air circulates throughout the entire seat. This overcomes the traditional drawback where ventilation holes would get blocked when sitting, trapping heat. By allowing air to pass through the entire seat surface, heat generated by the human body is efficiently dissipated, continuously resolving unpleasant 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 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 large 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. "Three-part structure" allows the seat cover to be completely washed.

What cannot be avoided during summer driving is the accumulation of sweat and odors on the seat. Many products faced challenges with difficult maintenance, but SPEEDER achieved complete separation with a "three-part structure" of "air-blowing fan," "seat body," and "seat cover." If it gets dirty, simply remove the fan and wash the seat cover directly. You can maintain new-like cleanliness and comfort throughout the season.

Compact & reduced noise. A driving space that balances silence and comfort.

We have independently reviewed the fan unit design, achieving a more compact fan and reduced noise. Compared to commercially available general products, powerful airflow capacity is maintained while significantly reducing unpleasant operating noise. Even in the quiet interior of hybrid cars and EVs, it provides ultimate coolness without disturbing conversations or music.

During "idling stop" while parked, don't give up on coolness.

In recent years, with the spread of idling stop, the problem of air conditioning stopping while parked has rapidly increased. This product supports power supply from your mobile battery by using a separately sold USB power cable. Even when the car engine is stopped, it can operate solely on battery power. You can maintain your own comfortable coolness regardless of location or situation, while saving on gasoline costs.
