Yeah, if you didn't get EMS, don't be surprised if it takes a few weeks to get to you, especially since you're in New York. The international sorting center there can take a while, longer if the package gets flagged for a customs inspection.
If you're the impatient type like I am, it's generally worth it to use EMS for shipping from Japan. My HHKB Type-S with extra caps shipped on a Saturday and had the first delivery attempt the next Tuesday, and the cost was only $5 more than standard airmail and $12 more than SAL (surface, which can take months to arrive).
