If you cannot get down on your own, who knows where to look? When a hiker is overdue, the name of the mountain, the route and the expected finish time give searchers a place to start. Here is what a Japanese hiking plan contains and how to file and share it.
How a hiking plan helps
A hiking plan is called a tozan todoke or tozan keikakusho. It lists the area, route, dates, group and emergency contacts. You file it through a channel accepted for the route. Writing it helps you spot problems before the hike. If something goes wrong, it gives rescuers specific information about where to look.
Japan’s National Police Agency asks hikers to submit their plan and share it with companions and someone at home or work. A planned ridge, hut or descent gives searchers a starting point and helps them narrow down the area.
People need rescue on low mountains and day hikes too. Share where you are going and when you expect to finish, even if the route is close to home.
Three examples of how missing information can delay a search
These examples show what can happen when the route, destination or expected return time is unclear.
1. Nobody knows the destination. A family knows someone went hiking but cannot say which mountain. The first task is to find out where to start looking. Short winter daylight makes delays particularly difficult.
2. The route changes and nobody hears about it. The filed plan follows a ridge, but the hiker takes a riverside trail instead. Searchers may focus on the ridge first. Share changes as soon as you can do so safely.
3. A solo hiker leaves no plan. Friends may not realize a hiker is missing until a missed appointment or work shift. An agreed check-in gives them an earlier reason to act.
In each example, searchers lose time because a detail is missing. A plan gives them a trailhead, intended route and time window even if you cannot call for help yourself.
For documented incidents and nationwide figures, consult the relevant prefectural police and the National Police Agency.
How to file a hiking plan
Prepare the plan before you leave home. Check the official instructions for the area and save a copy on your phone or on paper.
Common options include the following, depending on the route.
- Trailhead submission box. Where accepted, leave the completed form in the designated box before starting. Check ahead that the box is available.
- Online filing. Use the prefecture’s or police department’s accepted website or form. File while you still have internet access.
- Hiking app. Some authorities accept plans through a service such as Compass or YAMAP. Check whether creating the plan also sends it to the authority, and verify that you have submitted it.
Include the details required by the authority, such as names, addresses, emergency contacts, dates, planned route and group members. Add overnight stops, important equipment and alternate ways down where relevant. Share personal information with the official recipient and the people who need it in an emergency.
Some prefectures require a filing by ordinance. Gifu requires it for designated routes on the Gifu side of the Northern Alps and in areas of Ontake, Yakedake, Hakusan and Norikura. Failure to file or a false filing may carry a charge of up to ¥50,000 where the ordinance applies. Nagano requires filing for its designated trails. Check the current official map, rules and accepted channels for your exact route.
Keep the plan useful
Agree on how your group will handle changes and what your contact should do if you are overdue.
- Report route changes. Update the filing if the service allows it and tell your contact when safe. If there is no signal, tell hut staff when appropriate and contact your designated person once you can.
- Give a specific finish time. Say, for example, “I plan to be at the trail exit by 16:00.” Agree on when the contact should call for help if you have not checked in.
- Give a copy to someone you trust. Share the same route and schedule you filed. Let them know when you are down safely.
Before your next hike
A hiking plan is information that can give a search a head start. File it where appropriate, give a copy to someone you trust and tell them if the plan changes.
Start with the next outing, even if it is a day hike. Know who will notice if you are late, which route they will give to the authorities and how they can reach you.
