2. Environmental Protection Rules

The race course passes through valuable natural environments, including areas designated as national parks and habitats of rare plants and wildlife.

The following rules have been established to prevent adverse effects on irreplaceable forest ecosystems.

Participants must fully understand the purpose of these rules and comply with them at all times.

The use of trekking poles is prohibited in order to reduce impact on the trail.
Leaving the designated trail is prohibited. No-passing zones and other restrictions may be established where necessary for environmental protection.
Collecting or damaging plants, animals, fungi, rocks, or any other natural objects anywhere on or around the course is prohibited.
Cutting corners on the course is prohibited because it damages vegetation.
Do not litter under any circumstances.
Use the toilets provided at aid stations. If this is unavoidable, use a portable toilet. Any toilet paper used must be carried out.
Participants are asked to help reduce carbon dioxide emissions by using public transportation or carpooling.
Within the national park, nature conservation and appropriate use are promoted under systems based on the Natural Parks Act and other applicable regulations.
Even if the race can be held safely, the organizers may establish walking-only sections, alter the course, or cancel the race if trail conditions are considered unable to withstand use by a large number of participants.

3. Consideration for Other Trail Users and Race Participants

If you encounter a runner who is unable to move because of injury or illness, give priority to assisting that person.

Show respect and gratitude to race officials, local residents, volunteers, and everyone who supports the race.
The course is not reserved exclusively for the event. Participants must understand that it remains open to the general public and must not obstruct other users. When passing others, do so only in a safe location and walk rather than run. Always greet others when passing or meeting them.
Take care not to damage any structures or facilities located along the course.
Do not enter any area outside the designated course.
On paved roads other than sections where road-use permission has been granted, participants must use the sidewalk. When crossing roads, always follow the instructions of course marshals.

4. Rules for the Namerizawa Pass–Gotōyama Section within the National Park

The entire national park area used by the course, from Nihonsugi Pass to Darumayama Kōgen Rest House, is designated as a Special Zone.

In particular, the section between Namerizawa Pass and Gotōyama contains a valuable Pacific-type beech forest, including a well-developed Hydrangea hirta–beech plant community.

Several giant beech trees with a diameter at breast height exceeding one meter grow along the trail. A wide variety of trees, mosses, and other plant species form a complex forest environment, making this section one of the key areas supporting biodiversity in the Amagi mountain range.

The unique forest landscape represented by these giant Pacific-side beech trees is rarely found in modern Japan, where development has progressed extensively. It is a natural heritage site that must be preserved for future generations.

To protect this natural heritage, overtaking is prohibited in principle between Namerizawa Pass and Gotōyama.

Participants must fully understand the purpose of this rule and comply with the following:

The Namerizawa Pass–Gotōyama section is designated as an “Overtaking-Restricted Section” for the protection of vegetation and the trail.
- Overtaking is prohibited in principle.
- As an exception, overtaking may be permitted where the trail is sufficiently wide and there is no risk of damaging vegetation or the trail.
Patrol monitors will be stationed within this section.
- Patrol monitors have the authority to stop any participant who fails to comply with the race rules.
Some parts of this section may be designated as walking-only sections.

5. Rules Regarding General Hikers within the National Park

Although there are no explicit regulations prohibiting running on footpaths within the national park, these paths were designed primarily for walking and were not intended for running.

For this reason, when general hikers are present on the course, they have priority because they are using the path in the manner for which it was originally intended.

General hikers always have right of way.
Before overtaking, clearly alert the person ahead by calling out or otherwise making your intention known. Overtake only in a safe place and walk while doing so.
When meeting an oncoming hiker, give way in a safe place and allow the hiker to pass first.

6. Aid Stations and Medical Support

Three aid stations will be established for the ITJ70k and one aid station for the Around Alone 28k.

Food and drinks will be provided at the aid stations. However, participants in the Around Alone 28k are prohibited from using the food and drinks provided.

All aid stations will have toilets and first-aid stations.

To prevent the spread of COVID-19, only participants and staff may enter aid station areas. Spectator access and personal support are prohibited.

7. Course Markings and Guidance

With the permission of landowners and land managers, the organizers will install the minimum necessary marking tape, directional signs, and staff positions.
- Directional signs will be installed to guide participants.
- Ropes and other safety measures will be placed at hazardous locations in mountain areas.
- Staff will also be stationed where necessary. Participants must follow their instructions.
Distance signs will be placed approximately every 5 km.
Participants must follow all signs indicating no-passing zones and other restrictions.
Runners may be stopped at intersections or other locations. Follow the instructions of staff.
Course markings will be installed shortly before the event and removed promptly after the race.

8. Rescue and Medical Assistance

To ensure the safe operation of the race, the Race Executive Committee will make every reasonable effort to prepare the course and establish rescue and medical support systems.
- Participants must fully understand that trail running takes place in a natural environment and involves inherent risks.
- Each participant enters the race at their own risk and is responsible for injuries, illness, accidents, and other incidents.
First-aid stations will be located at all aid stations, with a doctor or nurse on standby.
- These stations will be connected to race headquarters by radio or telephone.
First aid may be provided to any person involved in the event who is in danger, regardless of whether that person is a registered participant.
- Depending on the location and circumstances, it may take a considerable amount of time for assistance to arrive.
- Any participant treated by a doctor or medical responder must consult a medical specialist after the race and report the diagnosis to race headquarters.
Doctors and medical responders have the authority to stop any participant whom they determine is unable to continue safely.
- In such cases, they may collect not only the timing chip but also the participant’s race bib.
Participants who withdraw may return to the finish area by sweep bus or support vehicle.
- Any taxi or other privately arranged transportation must be paid for by the participant.
If the organizers determine that a rescue team is required, one may be called.
- Any costs incurred may be charged to the rescued person.
If race headquarters cannot be contacted, participants may directly call emergency services, including 119.

9. Tracking Participants and Identifying Missing Persons

IC chips will be used to record the number of starters and finishers and to check participant passage at each aid station.
The system can identify individual participants by matching their name with their race record.
Participants must wear their IC chip throughout the race.
After finishing, place the race bib with the attached IC chip in the designated collection box.
If the IC chip is lost, the participant may be charged the actual replacement cost of JPY 2,200.
Participants who withdraw must return the IC chip to a nearby staff member or place it in the collection box at an aid station.

10. Withdrawal from the Race

Participants withdrawing during the race must do so at an aid station whenever possible.

When withdrawing, participants must submit the race bib with the attached IC chip to a nearby staff member.

If a participant must withdraw on the course for unavoidable reasons, they must report this to a nearby staff member or race headquarters.

The second race bib must be kept because it is required to collect checked baggage.

Withdrawal at an Aid Station

Inform aid station staff that you are withdrawing.
Submit the race bib with the attached IC chip.
You may return to the finish venue by shuttle bus or sweep vehicle.

Withdrawal on the Course

If withdrawing on the course, report this to a staff member or race headquarters.
Participants who are able to move independently must proceed to the next aid station or return to the previous one.
- Participants who cannot move independently must follow staff instructions.
- Rescue and evacuation from the course may take a considerable amount of time.
- If you are uncertain about your physical condition, declare your withdrawal at the previous aid station rather than continuing.
