How long does it take to get something from Japan to New York with Other Intl Shipping? -

I bought a keytar yesterday from Japan on ebay and I have no idea how long it will take to get to New York.

I buy in Japan and sell for other countries and with EMS I have Sent on sunday and arrived in Pennsylvania for Thursday. So, from 5 to 7 days I guess. You should start to worry if it takes more than 10.
