Sounds like you chose the cheapest shipping option from Japan the seller offered, or maybe the seller did not offer another shipping option. There are four different shipping options Japan Post offers, Express Mail Service ( EMS), Airmail, Economy Air( SAL), Surface Mail, so if it has been 30 days, the seller sent it surface mail, which means it was transported by ground to the port, loaded into a container ship, and then once it reaches the USA, will be put in a trailer and transported by ground to its destination. SAL, that is a combination of surface and air, surface in Japan, air to the designation country, and then ground to its destination, and I have heard, I dont know how much truth there is to this, but SAL packages are the last to get loaded and only if there is room, if not, it waits for the next air cargo container. Or the short of it, yes, its on the slow boat from Japan.
