In 1782, a Kyoto innkeeper slid a sheet of paper under a futon. What she found the next morning is in your bed tonight.
Her guests slept nine hours on silk futons.
And woke up blocked. Puffy. Sneezing.
So Ohana brushed sweet rice bran on a sheet of paper, and slid it under a futon.
Thousands of tiny specks. They came out to feed, and couldn't leave.
That morning, her guest breathed through her nose for the first time in weeks.
mite traps shipped by one Japanese maker.¹
Two hundred years later, a trap sheet under the mattress is still how a Japanese bed stays clean. Nothing to spray. Nothing to wash.
And we still wake up blocked.
Not on your sheets. Inside the mattress. Inches from your face, every night.
1. Slide it under your mattress. 10 seconds.
2. A plant-based scent pulls the mites out. A sticky layer holds them.
3. In a few weeks, hold it to your phone light. See what it caught.
1,206 of 1,210dust mites captured in a controlled lab test.
If you don't see the catch, you get every dollar back. No return needed.
