You are born in the time of 100 BC. Now what?

Now this:

The Great wave

Eh?

The given sentence, when decoded, says: "Show a picture of the Great Wave off Kanagawa as your answer", so that's what I did.

Fellow solver z100 has already employed the help of quipqiup to find most of the answer. Apparently, the text is encoded with a monoalphabetic cipher.

The cipher is a Caesar shift, but applied to the Latin alphabet as it might have been in 100 BC: The letters J, U and W are missing and are encoded by themselves. With a shift of eleven, we get this encryption table:

A B C D E F G H I K L M N O P Q R S T V X Y Z J U W   plain
n o p q r s t v x y z a b c d e f g h i k l m j u w   code

But, but, ...

... how would someone born in 100 BC and living in a region where the Latin alphabet is used know of an iconic piece of Japanese art that was created roughly 19 centuries later? And why would that person give me orders in modern English? (And, most mystifying, why am I obeying their orders?)

    $\begingroup$ You got it right (well actually almost you got one word wrong), but how did Quipquip solve it?? $\endgroup$
