The recent shift on steam to using yen instead of dollars in Japan has caused all your prices to go insane (more so than usual 
):
Click for big
The Logan’s loonies should be 1,999 yen, which is about $20, not the 199,900 yen it currently is, which is $2,000…
Everything is off by 2 decimal places.
Thanks for the report. We’re looking into this now.
It looks, at least initially, like this is a display problem. If you click one of these, the Steam dialog that appears should ask to charge you a more reasonable price (1/100 of what’s displayed there). Let me know if that’s not the case, and we’ll see what we can do about the display in the meantime.
That does seem to be the case. I notice in the steam dialog they use decimals (“100.00 yen” etc.), despite there not really being any denomination smaller than 1 yen, maybe that’s where the issue stems from?
Is this fixed for you now? It’s difficult for us to test how things look in the Japanese store on Steam.
