The listed cordinates should have you standing in front of a sign board explaning the history of the above painting.
The Cache: I have made this cache a nice easy multi, that way I could bring your attention to an interesting Mural.
What you will ned to do is note what DAY the mural was launched.
IF - Wednesday COORDINATES ARE S38 23.153 E142 28.674
IF - Thursday COORDINATES ARE S38 23.192 E142 28.805
IF - Friday COORDINATES ARE S38 23.183 E142 28.718
At certain times of the day this cache may NEED STEALTH to grab.
Good Luck and Enjoy.
