Carlock, a car-side tent, has been available for pre-sale on the Japanese crowdfunding site “Makuake” since September 29, 2021, and is gaining popularity with sales exceeding 9 million yen. The unique feature of the Carlock is that it is a pop-up type and the three sides of the tent become a tarp. Car-side tents are a popular category this year, with a variety of manufacturers, from major players to venture companies, releasing products.
