gizmodo.jp (Japanese)

A Japanese article reviews three products designed to cool parked cars during extreme summer heat, addressing the common problem of vehicle interiors becoming unbearably hot. Featured items include a Seiwa sunshade using Ladycool radiative-cooling technology, reflecting sunlight and radiating heat without energy. Two headrest-mounted fans are also highlighted: EXEA's 340-degree rotating stick fan and a dual-fan model with independently adjustable angles. The article, originally published August 9, 2025, notes rear seats heat faster than front ones. The cable-powered dual fan has no battery, eliminating fire risk in hot vehicles.
