Akira (aka Arti) is a great guide. Very knowledgable of the area, kept on schedule, and provided us all of the points in the itinerary. He had fun stories and was great with conversation. He even provided some pointers for shopping for specific souvenir items. Although it is an extra few hundred dollars, the private taxi is worth his recommendation for the Mt. Fuji area - we wouldn't have been able to see everything without it.
