Hello Supaplex, the original edit by 日本ボール would be a vandal/imaginary route it seems.

The ferry route between 与那国島 and 台灣 is in discussion (available as demonstrated in early 2024?), so I would like to remove this ferry route at this time.

Do you have any idea?

P.S. On the other hand, this route would be very nice if available. I hope this could be real!
