Green Dragon Society
from Emerald-Hammer Website
The Order of the Green Dragon (or the Green Dragon Society depending on your source) were/are a Japanese secret society dedicated to the mastery of the human body, and of the Time Organism or the Etheric Body. Mastery allowed access to great power apparently.
They also had powers of prophecy.
Other sources suggest that they were able to control the elements within their bodies (I think that these may have been the five oriental elements rather than the four western elements). Higher level initiates had to prove themselves by forcing a seed to germinate by their willpower.
The Japanese order is
distinguished from western secret societies by it's exacting demands -
especially the price of failure.
Haushofer was a military attaché in Tokyo when he joined before WW1.
Later Haushofer was a Nazi
and was influential in forming Nazi racial policy. Haushofer was also a
member of the Vril Society or Luminous Lodge. The Vril Society is
supposedly one of the sources of the Nazi party with early party members
overlapping with the Vril, Thule and other secret societies. 
It's foremost adept was
known as the Monk of the Green Gloves/Hands , who
was renowned for his clairvoyant abilities and had mastered prophecy.
Hitler had audiences with him.
This may have due to the failure of the Tibetans to alter the course of the war, or it may have due to the involvement of Haushofer's son in the 1944 assassination attempt on Hitler. Some sources say that they were put on concentration camp rations. It is reported that when the Russians entered Berlin in 1945 they came across numerous bodies of Tibetans.
They had all committed
suicide by a knife stroke to the stomach. Some sources say the monks
were in German uniform without insignia, other sources say they were
naked. Because of his failure, Haushofer killed his wife and then
committed seppuku himself at the end of the war, as would be expected by
the Green Dragon Society.
