Why no-drill tension mount is the first filter

For renters, dorm rooms, and short-term stays, the strongest search term is つっぱり式. It means the shade is held by pressure inside the window frame, so you can often avoid screws and wall damage.

No-drill does not mean no checking. A tension shade still needs enough frame depth, a flat contact surface, and a window frame strong enough to hold the product during daily operation.

つっぱり式Tension mountMain no-drill installation type for many Rakuten listings.
穴あけ不要No drilling requiredUseful for rental housing, but still read the installation limits.
コードレスCordlessCleaner look and fewer hanging cords around the window.
1級遮光High blackout gradeHelpful for bedrooms, but side gaps can still leak light.

The fit checklist is more important than the color

Measure the inside width in three places, measure height in three places, and measure the usable depth of the window frame. If the frame is uneven, use the smallest reliable measurement.

On Rakuten Japan, some sellers ask for the frame size while others ask for the finished product size. Read the measuring diagram before converting inches to centimeters.

  • Inside width: check top, middle, and bottom.
  • Inside height: check left, center, and right.
  • Depth: confirm the minimum depth required by the tension unit.
  • Obstacles: check window handles, locks, air-conditioner pipes, and inward-opening windows.

Price and shipping checks for overseas shoppers

The lowest price shown in search results is often the entry size. The final price can change after you choose width, height, fabric, and operation type.

If the seller does not ship directly outside Japan, plan a forwarding route before ordering. Large custom window products can have size limits, so do not assume every forwarding service will accept every shade.
