Marufuku was founded in 1952 as an agricultural workwear manufacturer. Initially developed in 2001 in response to the demands of female farm workers for a mask that is easy to breathe while preventing sunburn, Yakenu masks have now become a long-selling product with over 300,000 items sold annually and are widely used in various occasions such as sports, outdoor activities as well as to prevent sunburn in everyday life. The patented two-part design not only prevents the feeling of shortness of breath while wearing it, but also lets you drink without having to take it off. It also keeps your glasses from fogging up. The special made-in-Japan material with titanium kneaded into it provides semi-permanent UV protection while also feeling three degrees cooler than normal polyester. Also, in the time of COVID-19, the masks are widely appreciated as they allow you to enjoy playing sports with peace of mind as they can protect you from airborne droplet.
