I hope most people are safe. It is sad to hear of deaths and we know it lies on a very high risk area but it is so beautiful to visit.
We are also concerned as we have tickets to go next week and do not know if the area is open for visitors.
I have not been able to contact the Ryokans
Where are your ryokans?
Have you contacted them and not received a response?
Or do you mean that you have not been able to contact them - perhaps because you do not have an email address?
Certain areas, particularly in Northern Osaka, are affected more than others. These include Takatsuki, Minoo, Ibaraki city, Settsu and Suita.
The Osaka area has been told to expect further earthquakes within the next week, with the warning that the coming earthquake may well dwarf this one.
If you have actually contacted your lodgings but received no response to reassure you, this might be the time to reevaluate your itinerary.
