Hi Laurie!
This is a site for people to get answers from numerous people and not really a place to speak directly. In the “Discussions” tab of the Japan group, feel free to create a question for each topic you have and we can help you get answers! (Obviously, to protect your client’s privacy, please be careful to not give any information without permission or be vague enough to not give any information to identify them.)
If that isn’t a possibility for this client, you can add me as a contact and message me. I can put you in contact with some travel agents who could possible consult (they will likely charge a fee though).
