Does something like this exist here in Japan?
This is the Australia version, most of this is commonsense! (a mystery here).
Skier/Snowboarder
Safety Responsibility Code
Snowsports can be enjoyed in many ways. At ski areas you may see people using alpine, snowboard, telemark, cross-country or other specialised ski equipment, such as that used by disabled or other skiers. Regardless of how you decide to enjoy the slopes, always show courtesy to others and be aware that there are elements of risk in skiing that common sense and personal awareness can help reduce. Observe the code listed below and share with other skiers the responsibility for a great experience.
1. Always stay in control, and be able to stop or avoid other people or objects.
2. People ahead of you have the right of way. It is your responsibility to avoid them.
3. You must not stop where you obstruct a trail, or are not visible from above.
4. Whenever starting downhill or merging into a trail, look uphill and yield to others.
5. Always use devices to help prevent runaway equipment.
6. Observe all posted signs and warnings. Keep off closed trails and out of closed areas.
7. Prior to using any lift, you must have the knowledge and ability to load, ride and unload safely.
Skiers and Snowboarders found skiing/boarding out of control and/or behaving recklessly will have their tickets confiscated.
KNOW THE CODE. IT'S YOUR RESPONSIBILITY.
I spend 90% of my energy watchin everybody else around me just cuz I know they aint lookin.
Know this feeling!
I also notice that gondalas give great acsess to the mountain for everyone- even first timers (read: no experiance necessary)
Everyone has to start somewhere but somewhere safe! Eg I saw 3 young kids no older than 10, unstrapped from there boards (no board leash- not necessary in Japan?) slowing sliding on their butts down a steep section which is a blind spot from above! Responsible parenting...! Luckily I stopped on the side to wait for a mate and warn him. Scary. I see boarders inparticular flying down this course with little regard for other people. Made me cring!
PS I am a boarder, no bias here!
