It would be best if you were to list the actual patent number so we could check your interpretation. That said, if it is a Japanese patent and there is no US equivalent then it should not impact your ability to market a product in the US assuming you aren't manufacturing in Japan. It doesn't matter whether the Japanese patent has expired or not as patents are country specific. The patent owner cannot now file for a US patent on the same invention since the Japanese patent represents prior art.
While the specific Japanese patent shouldn't be a problem, it doesn't mean there aren't other patents which are. While you can and should do more patent searching on the specific technologies being employed, it might be a good idea to employ an actual patent attorney or agent to perform a "freedom-to-operate" assessment. At the very minimum, I would search under the inventor's name for US patents.
The cited document JP3174302U is a Japanese utility model, not a patent. With regard to fees, the following quote comes from the Japan Patent Office.
(i) for patents
A patent right can be maintained by paying patent fees on an annual
basis, starting with the fees for the fourth year. However, if the
patent fee for a certain year is not paid within the deadline, a late
payment equivalent to double the patent fees can be made if the late
payment is paid within six months after the original deadline to pay
has expired. If the late payment fee equivalent to double the patent
fees is not paid within the within six-month period mentioned here,
the patent right will be deemed to have expired as of the original
Furthermore, when you, the patent-right holder, have a justifiable
reason for not paying within the six-month grace period, i.e. where
the Patent Office finds that your failure to comply with the time
limit occurred in spite of due care required by the circumstances
having been taken, your patent right can be restored. In other words,
you can pay the patent fee and the patent surcharge within two months
after the date on which the justifiable reason ceased to exist, as
long as this is done within one year after the six-month grace period
expired. In doing so, you are required to submit also a document
called Statement of Reasons for Restoration indicating the justifiable
(ii) for utility models
The answer given for patents applies to utility models also.
According to Epacenet, the non-payment of fee happened on 2015/02/22. Since it is well past 1 year and six months, I don't think it is possible anymore to restore the status of the utility model. Just to be clear, I am not an attorney and this answer isn't legal advice.
