Original pajama brand "Pajama-ya IZUMM" (https://www.pajamaya.com/), operated by Flex Co., Ltd. (Representative: Izumi Kumasaka, Headquarters: Sagamihara City, Kanagawa Prefecture), is challenging itself to "create the world's best sleeping pajamas."
Our company endorses "April Dream," an initiative to make April 1st a day for announcing dreams. This press release is the dream of Flex Co., Ltd.
## We want to eliminate sleepless nights
Nights when you can't settle down even after getting into bed. Nights when you wake up suddenly due to heat or cold. Nights when you greet the morning thinking, "If only I could have slept more."
We want to reduce such "sleepless hours" as much as possible.
With this desire in mind, Pajama-ya IZUMM has continued to make pajamas with a focus on materials. For over 20 years since its founding, the company has consistently faced "sleep" without being influenced by trends.
## "To sleep is to live"
A day begins with "sleep."
No matter how busy the day, no matter how hard you worked through the night, if your sleep is not regulated, you will not be able to perform at your best the next day. It's not just about performance. Mental well-being and physical recovery all depend on "how well you slept."
That's why Pajama-ya IZUMM wants to spread the culture of valuing sleep more, both in Japan and around the world.
## We are convinced of the power of pajamas
"How can one sleep comfortably?"
With this question, we have researched sleep from all angles of pajamas, including materials, sewing, silhouette, and feel.
In the process, we also realized that sleep involves all aspects of "clothing, food, and housing." Meals, daily activities, and the bedroom environment—all are important, and a truly good night's sleep cannot be created by focusing on just one.
By arranging "clothing, food, and housing" for sleep, and by greeting a good tomorrow with sleep. As we expanded our vision to create a place where people can experience and learn about sleep, we realized anew:
**"Pajamas have the power to change sleep."**
