Ten-minute walk to Kencho-ji from Kita-Kamakura Station, where you have to pay 300 yen to enter the temple precinct. Enjoy the temple and buildings, then walk another ten minutes up a path (say hello to the frog along the way!) and long stairway to the coordinates (Beaked Guardians).
Step 1: Count the number of Beaked Guardians. This is 'B' (for beaks!).
Guardian's Hi Five !
Step 2: To find the actual cache (Kencho-ji moat), calculate the following:
Y = 19.798 + B/100
X = 33.394 - B/100
Kencho-ji moat coordinates are:
N35 Y (latitude minutes)
E139 X (longitude minutes)
Don't forget to get a goshuin at the Kenchoji entrance and at the temple above the guardians.
Go for it!
