I added a tiny X to the Chart/map because too many folks had a hard time locating Sofu Gan..
-------------------------------------
I purposely did not include an "X marks the spot" because the Lot's Wife, Sofu Gan, or Sofu Iwa text is right there if you zoom in a little. Plus you get the excitement of finding it yourself.
If you zoom out to the "small squares" of Lat & Long you will see Tokyo. Tokyo is approx 35-30 N, and almost 140E. You can find Tokyo, right? Count down 6 "squares" from Tokyo to the 29N - 30N, 140E - 141E "square" and zoom in a little. There is shallow water that rises up 1,000's of feet from the ocean floor at that location and Sofu Gan is on the highest pixel.
I know I made a screenshot of the map so I'm going to go find it and add it to this message. So I don't get nit picked on this, I realize Lat/Long are not squares and the Earth is an oblate spheroid, but for SH4 remedial geography I'm callin' them squares and that's my story and I'm stickin' to it.
Close up:
The Dev's really got this close.
Regarding detail, USS Tuna did a special mission in the Java Sea area on Sanbergelap Island and if you zoom in real close that tiny island is on the SH4 map too. I truly believe they had intentions of going into much more detail with SH4 including these landmarks - if only they had the budget.
Well, good luck finding Lot's Wife - I'm confident now that you will.
Happy Hunting!
