Here is "Ojima 6 Chome Danchi".
------------------------------------
Step 1
If you arrive at the park, you need to find the "Water Supply"
sign.
The "Water Supply" sign is NOT only one. You need to search
ALL.
Q1) How many "Water Supply" signs exist in this park? Answer
=> (X)
*** Don't forget to make a memo the numbers (a) (b) (c)
...***
------------------------------------
Step 2
If you finish to search ALL the "Water Supply" signs, find
another type of signs next. (See pictures below and it must be 1 to
7.)
Move to the sign which is (X).
------------------------------------
Step 3
Now you need to calculate.
Q2) What is the number (Z)?
------------------------------------
Final Step
You must be near the sign (X) now.
Walk toward NORTH (Z) then WEST (Z) steps with long
stride!!
Good luck!! :D
