Typhoon 8 should be arriving in Okayama on Thursday. It is already losing strength and will probably continue to do so as it moves up the coast of Japan. Being that Shiraishi Island is in an inland sea, usually the typhoons lose their strength by the time they reach us.
The ferries to the island will stop, but it's hard to say when as it depends on the conditions of the typhoon. We'll keep you posted and let you know as soon as we hear about the ferry schedule.
The Moooo! Bar on the beach is closed until further notice. We're thinking everything will be clear by Friday.
