Divide into world area into tile shape, escalatory and express in binary. Usually, tile areas are not exactly mesh-type dividing like other GEOCODEs, and have some overwrap part. This does some correction to make target area nearly square. (Simple dividing without correction causes divided area into trapezoid shape.)
Finally, use 64 kinds of Japanese Hiragana characters, translate each 7 bit binary into one Hiragana Characters. This makes total code length short, and convenient if code is used in Japan.

Sample Code: (Japanese Hiragana characters)
