Troyus,
While you are in Japan it is well worth the effort to visit the Sado gold mine off the west coast.
The Mitsui Gardens and Adachi Museum are absolutely the best in Japan (if you like gardens ) Make the effort no matter how much it costs.(walk around the external perimeter to appreciate the borrowed landscape.)
Visit the Kanazawa Gold Leaf Factory

you will love it.
