Japan, Seimonoshki Picture Postcard. Need Help

Please help!I cannot find anything about the City named Seimonoshki (Google immediately corrects that it supposed to be Semonoseki). In addition, need help with cancelation dates

16.8.14
3.8.15

Is it possible that it had been traveled a half of the year? One of the cancelation marks appears including "MAS..." or am I wrong?
I will appreciate any of your comments or suggestions. Thank you!

There is a Shimonoseki. That might be it. (The Romanization of Japanese words varies over time.)

I'm afraid I'm a little short on time at the moment to try to make sense of the dates, other than to say that (1) Japanese cancels typically read date.month.year, and that, (2) on cancels that use Japanese characters (as opposed to the Roman alphabet), they often (although not always) refer to the year of the Emperor's reign (the so-called regnal year), rather than the calendar year as we know it.

You could try Googling to understand how to convert Japanese regnal year to Western calendar year.

I'm sure someone far more knowledgeable than I will be able to provide far more helpful information soon!

Ok, that cancel that you can barely see, and appears to end in "IO", is probably "TOKIO", as it was sometimes Romanized (and more typically so at that time). So that "14" is 1914, which is also Taisho 3, which appears in the first position of the Japanese-writing cancel. So it's in the order of year-month-day. (It always goes either smallest to largest increment of time (i.e., day-month-year), or largest to smallest (year-month-day). It rarely (never?) goes with the American style of month-day-year (medium-smallest-largest).

Thank you very much!
You are the best! ))

You bet!

(And thanks for coming back to thank us. So often people don't do that, and I never know whether or not they actually saw the replies or just moved on to another site.)
