Having never wandered in such an area, I would like to go see it closely.
QUESTION: How to get close to it?
Taking the ferry from Ishigaki to Kohama then walking sounds like the easiest, but I am not sure one can "see" a mangrove on foot. The best would probably be kayaking/canoeing, I guess, but I haven't found any rental place.
Alternatively, are there more accessible mangroves accessible as a day trip from Ishigaki city?
