Since the only toilets available on the course are at the A1 HQ Aid Station and the A2 Ninosawa Forest Road junction Aid Station, all participants must be prepared and carry their own disposable toilet kit.

In addition, it is not uncommon for road conditions to deteriorate depending on the weather before and during the event.
We strongly recommend trail running shoes as road running shoes can cause significant damage to the shoes themselves and there is a high risk of direct injury to the feet, falls and serious accidents. - poles
This is a course with many steep inclines, both up and down, and is especially effective for the second half of the course when you are feeling particularly tired. We recommend this especially for beginners who are not used to trails.

(Hirayama Junction to Himara-yama, about 2km section)
A section of the mountain trail used for the 40km and 60km courses (around Hirayama, Himara-yama and Bunzou-dake) is a special protection area of the Daisetsuzan National Park.This area is home to rare alpine plants, such as Komakusa, especially around Hirayama and Himara-yama.To protect these plants, this section is a no-run zone. Please understand the purpose of this and strictly follow these rules.

- The section from Hirayama Junction (CP3) to Himara-yama is a “no running” section in order to preserve the vegetation and hiking trails.
- Timekeepers will be stationed at the entrance (Hirayama Junction) and exit (Himara-yama) of each section. Your number card must be read when entering and leaving the section. Please follow the instructions of the officials.
- If you pass through the section within 30 minutes, your time will be recorded as 30 minutes. If it takes longer than 30 minutes, the time recorded will be the time taken to pass through the section. In other words, no matter how fast you are, at least 30 minutes will be added to your time.
- Marshals will be stationed along the course. If a violation is found, the marshals have the authority to impose penalties, up to and including cancellation of the race.

Questions and Answers
- Are there any rules regarding the shape or capacity of the required water cup?
-
40K and 60K participants are required to bring their own personal drinking cups. Aid stations will provide bottled water and sports drinks, which participants are expected to pour into their own cups and drink.
Drinking directly from the bottle, even without touching your mouth, is prohibited as it may contaminate the bottle. Please ensure you bring your own personal cup.
As long as the cup is suitable for its intended use, the size and shape are free. It does not have to be a trail running cup; for example, an aluminum Sherpa cup designed for outdoor use is also acceptable. Personally, I like Sherpa cups because they have a travel vibe. Aluminum cups can get scratched, but they are lightweight, so I recommend them.
Additionally, there are no restrictions on the amount of water you can carry, so you may refill your flask or hydration pack with over 1 liter. Please ensure you have sufficient water supply.
- If I am not feeling well on the day of the event, can I change to a shorter distance category?
What happens if one member of a pair cannot participate? -
You may change to a shorter distance category.
However, you must notify us during the check-in period for the original category in which you registered. Your bib number will remain the same; only the category will change. If you wish to change categories in advance, please contact us as soon as possible to ensure a smooth process.
Please note that no refunds will be issued for any difference in fees. It is not possible to change to a longer distance category.
If you or your partner becomes ill or experiences other unforeseen circumstances that prevent you from forming a pair, you may switch to the solo competition in the same category (e.g., 40K Pair to 40K Solo or 60K Pair Relay to 60K Solo). You cannot switch to another category in this case. Additionally, for changes from the 60K Pair category to the Solo category, you will be billed for the difference later.
- I am not sure if the specifications of my rainwear meet the performance requirements listed as mandatory equipments. How can I confirm that it is safe to use?
-
Rainwear is designated as mandatory equipment because it prevents participants from encountering life-threatening situations in the mountains during inclement weather.
Manufacturers do not measure the performance of rainwear according to uniform standards, and it is impossible to objectively evaluate the performance of all products because each company is developing its own materials at a rapid pace. The most reliable method is to consult the manufacturer. Conversely, products from manufacturers who cannot answer questions may not be suitable for use.
When visually checking mandatory items, we use the following guidelines: checking for waterproof zippers and taped seams. However, staff checks are intended to identify items that are clearly not rainwear for outdoor activities, such as windbreakers or casual rain gear, or participants who have not brought any rainwear.
Setting mandatory items as part of the event regulations prevents participants from facing the worst-case scenario in an emergency. Please review the rules and waiver form again to ensure you have all the required items.
