TL was a little tricky. I think some emergency response jargon may be in use, and some of the translation depends on that assumption. I don't get "次はここだぞ!!", literally "Next is here!!", at all.
We can't restore communication with Honshuu!?My God, an EMP...Follow the drill, getting people to shelter is the highest priority.
The next is here!!
TL help needed
Fishing boats...?
Surveillance radar showing 4 contacts!!
I was only able to reach the base at Ishigaki Island*; their situation is the same as ours!
*Second-largest of the Yaeyama Islands, and home to a large Japan Coast Guard base.
No good!!
This would be an expected effect, in the event of nuclear attack.
-Yonaguni Island-
One of the Yaeyama Islands. The westernmost inhabited island of Japan, it is only 108 km E of Taiwan.
