A Crag Guide gives an extensive view of all sub areas and climbs at a point in the index. It shows a snapshot of the index heirachy, up to 300 climbs (or areas) on a single web page. It shows selected comments climbers have made on a recently submitted ascent.

At a minor crag level this should be suitable for printing and taking with you on a climbing trip as an adjunct to your guidebook.

The name translates as "Your lord rock"

Access Issues: inherited from Ogawayama

Much of the information about this crag is from the online guide http://www.ogawayama.com/

Ethic: inherited from Japan

There`s not a lot of information about in English on climbing in Japan. Much of the information is kept in personal blogs or is accessed through joining a climbing organization.

Many of the routes are well protected, while other less climbed "sport" routes have loose pitons as protection.

The Japan Free Climbing Association does a lot of good work (http://freeclimb.jp/seibi/seibi.htm) but with some clubs and communities, many techniques and ethics are still passed down from old generations with outdated gear and techniques.
