We don't know where you are posting from...but the diving situation sounds bleak...Too bad you can't make it to Izu...It's not quite like the Orwellian 1984 you are dealing with...more like a kinder, gentler 1984....dive safe...These friends who made their own club--did they do this to avoid the problem with fishermen, or a problem with the dive shop itself? Just trying to figure out how one would best pitch it to the shop....I'm still not entirely sure if the whole fishermen getting angry thing is the truth, or a load of BS so i haaaaave to pay them 14000 yen every time I want to go diving, instead of just whatever exorbitant amount they will charge me for tank rental....
