With tens of millions of people struggling with hay fever caused by cedar and cypress pollen across Japan, companies are perpetually coming up with new ways to survive the season of itchy eyes and runny noses.
At least a quarter of Japan's population of 123 million suffer from cold-like symptoms each spring because of the pollen dispersal, according to the Environment Ministry, which advises that people wear surgical masks, protective glasses and spend less time outdoors to defend themselves from the allergens.
But a paper company in Shizuoka Prefecture has come up with an alternative way of teaching defense against hay fever through illustrated toilet paper.
