I´m planning to travel to Japan by April and decided I would take the opportunity to do some divings. I was thinking mainly in Okinawa, and specifically Yonaguni as one of the spots to see. As I notice it is really close to Taiwan I was thinking to cross to Taiwan afterwards, but I´m not sure if there is any ferry or another fast and preferably not too expensive way to get there.
In short, I'm wondering if it's worth it to cross to Taiwan to avoid an innecesary "long" return to Tokyo before I return home, taking benefit of visiting another place in the process.
Could you please provide some advice?
Also, if there is any comment you would like to share about Japan I'll be glad to hear your experience
Thanks in advance
