Nota bene

I would like the use in consideration for nature to follow splendid natural environments.

1.Let's stop collection of the animals and plants

One one animal, plant inhabiting moor makes ecosystem and keeps natural scenery. The act that we have caught casually is the environmental disruption.
(note) collection of designated plant is forbidden by law (natural park method Article 13 Clause 3 tenth). For more details, please see the following link (Ministry of the Environment).

2.Let's walk tree way, the sidewalk

We establish tree way and the sidewalk installed in moor to protect moor. Seed, bacteria of weed which attached to shoes invade when we set foot in moor and may affect the animals and plants inhabiting moor. We need long time to put back the affected animals and plants. For similar reason, please do not put tripod, stick of camera in the moor either.

3.Pet does not bring

As pets such as dogs affect the animals and plants from reason same as the above, and allergy to animal and animal are a nuisance to user whom they are hard for to deal with, let's stop bringing to of pet.

4.Mountain paths from parking lot to moor may be slippery

Because mountain paths from parking lot to moor are unpaved, you become very slippery after the rain and the rain, and please be careful as you might fall down. In addition, step becomes easy to become dirty as muddy water becomes easy to splash. When shoes (boots and mountain climbing shoes) which may become dirty are worn, it is very convenient.

5.There are no water to drink, vending machine near the moor

There is restroom, but cannot drink because we use rainwater. In addition, please prepare for drink beforehand as there are not convenience store and vending machine near.

In addition, please do not wash mountain climbing shoes in washstand of restroom. Mud cannot use in drainage pipe that is washstand.

7.When it is dusky, bear may appear frequently

Because it is mountain, Asiatic black bears inhabit. Asiatic black bear is coward animal unlike appearance. When it is dusky, we act, and sense of smell and hearing are superior mainly. Therefore there is habit to evade when we sense sounds that there is not in the natural world. In addition, we seem to hide ourselves when human being goes along near the bear so that bear is not found in human being.
(note) when come across point-blank range, bear may attack in wonder.
I would like measure such as talking in carrying, large voice of bell and radio.
