Tsunami-Evacuation-Map or App for Okinawa

Dear community,

I'll be staying in Okinawa on the north-western edge of Motobu-Peninsular in october.
Since this is very close to the sea and basically on sea-level with very flat surface going inland, I've been looking for a map or app showing elevation numbers and shortest routes to higher ground in case of tsunamis.

I've done quite a bit of research, but doing so in english leads to almost no helpful results and switching to Japanese with google translate has washed up many things but not really what I was looking for or what can be easily navigated without knowledge of Kanji.

So, long story short: [b]Does anyone have a tip for a working app or website that shows tsunami-evacuation routes or at least elevation numbers, especially for Motobu-Peninsular (Bise-Region)?{/b]

So far I've tried the "Japan Shelter" App which crashes all the time - any experience with that?
Also I've come up with this PDF, which I suppose shows close to what I am looking for, but, well, it's a PDF.

This information will do, but I'd be more happy with a working App or website.

What's a fact in case of a tsunami-warning is to better get our skates on ....

As always thank you very much for your time and effort :)

In the meantime I found the following site which is very close to what I am looking for.
However, no escape routes can be shown, it cannot be translated automatically by google and it doesn't use location tracking from my phone.
But I guess for tracking elevation and estimating tsunami risk, this should be sufficient.
