The dealer may be confused as to what is required.
Before 2 Jan 2017, only Brazilian rosewood was CITES-controlled, and it was (and still is) in Appendix I, which has very stringent requirements for import/export.
After 2 Jan 2017, all rosewoods become CITES-controlled. However, other than Brazilian which remains in Appendix I, all the other rosewoods are in Appendix II. These Appendix II's do require some import/export licence if there is a commercial sale (ie the dealer selling to ordinary buyers). However, it's quite easy to get such licences. They only require some information to be filled in on a simple form, and a nominal fee to be paid. The requirements for Appendix II licences are far less onerous than those for Appendix I licenses.
I believe for Appendix I, the dealer has to have evidence/proof that the Brazilian rosewood was acquired prior to a certain date (in 1972 if I recall correctly - oops, found references that it should be 1992), and then apply for special export documents (in the US it's a Protected Plant Permit, Re-Export Certificate and maybe a photosanitary certificate), the cost of which is quite expensive. And in the US, the Appendix I's need to go through designated CITES ports.
A dealer in the US that I was working with to buy my spruce/IRW guitar from was initially confused and thought that he would need to meet the Appendix I high requirements, which he was not prepared to do (too much paperwork and also too expensive). It was only after I explained further (I did a lot of CITES research) that he clarified with Wildlife & Fisheries and found out the Appendix II obligations were much more manageable.
You may also try explaining this to your Japanese dealer, if you are comfortable doing so in Japanese.
