On July 20, 2026, Sina's Weibo account "Sina News" reported the appearance of a peculiar product called "Human Refrigerator" in Japan.

The article introduced this "Human Refrigerator" as having an exterior resembling a giant refrigerator, with its design inspired by vending machines commonly seen on Japanese streets. It stated that the device's interior is maintained at 15 degrees Celsius, and when one enters and sits inside, a cold air stream of approximately 5 degrees Celsius blows onto the head, neck, shoulders, and back, designed to rapidly cool the entire body in about 10 minutes.

It also mentioned that the "Human Refrigerator" is priced at 1.5 million JPY and is primarily sold to businesses.

The article introduced "Do Hiemon BOX," a personal cooling booth sold by Trusco Nakayama, a major Japanese wholesaler of tools and industrial equipment. It is reportedly sold mainly for heatstroke prevention in construction sites, logistics warehouses, factories, or municipal shelters and public areas.

Regarding this matter, Chinese netizens expressed widespread confusion over its abstract and unique development idea, with comments such as, "It's good that it's not horizontal, but it looks just like a refrigerated coffin for a morgue," "Did they get the inspiration from a coffin?", "Why do Japanese products always have such a creepy vibe?", and "If there's nothing to invent, there's no need to force an invention."

Furthermore, critical views were directed at its performance, practicality, and cost-effectiveness, with comments like, "You'd probably catch a cold just going in and out of this, and worse, it could cause cerebral infarction or myocardial infarction," "A sudden cold stimulus of 15 degrees Celsius contracts blood vessels in the skin, making it harder for heat to escape and worsening heatstroke," and "For 1.5 million JPY, you could buy dozens of air conditioners."

On the other hand, some users evaluated its practicality and value, saying, "At first, I thought it was just a quirky gadget, but upon learning more, I realized it's meant to prevent heatstroke for outdoor workers and construction site workers. I think the target need is very clear and practical," and "1.5 million JPY is expensive for an individual, but if a company buys it for employee safety and welfare, it's a perfectly reasonable amount."
