Prepare your sauna installation

Fire department paperwork

Enter your details, equipment and installation site to prepare four attachments for a Japanese fire department filing.

You file the notice yourself. Obtain the main municipal form, such as the notice of installation of fire-using equipment, from the fire department responsible for the installation address. Before construction, ask them whether a notice is needed and which form, deadline, copies and additional drawings apply. These vary by location and equipment.

Municipal guidance applies to its own area. Ask the fire department responsible for your installation address which filing and documents are required.

Preparing your fire-department paperwork

Prepare four Japanese attachments for an electric sauna: equipment, ventilation, heat source and installation summaries. Reference airflow is calculated from room volume using Q = V × 6.

The sources include Tokyo and Nagoya filing guidance and the HUUM manual. Six air changes per hour is a manufacturer guideline, not a statutory requirement.

Confirm the main form and additional drawings with the local fire department. Unknown fields remain marked blanks; the attachments do not guarantee acceptance or compliance.
