Okay, I have no reference fot this now.  As far as I know, the law
enacted in 1886 says that the standard time for general use in this
country is defined as the time on the meridian at E135 degree.
(This sentence may not be precise due to my bad English.)
At this time, Ishigaki is in the possessions of Japan.
It may be changed later, but maybe I can find it in Japanese law.
I'll report the result if I find it.

Actually, Ishigaki island is in Okinawa prefecture, and my friends who
have been to Okinawa main island said JST was used there...

Sorry, I don't know who (what?) Shanks is.  I heard from my parents
that DST was surely used right after the World War II.  But I don't
know the details either...

Now I understand the problems, so I will check these points including
Marcus island (Minami-Tori-shima: thanks for Japanese name!) when I can.
Thank you for your information.
