I've seen when I create a ticket for 100 JPY in your system, that it converts to 10000 JPY which is not the ticket amount I intended to display.

To appropriately display none USD tickets on your event page, you will need to enter the value of your ticket with the currency abbreviation immediately following it.
For example, to show 100 JPY ticket on your site, you will need to place 100JPK in the ticket amount field of your event page.
The JPY will disappear and the ticket amount will be accurate.
