Where to study yakuzenryouri?

日本に行く時は薬膳料理を勉強したいのですが、どこで勉強できるでしょうか？　
I want to study yakuzenryouri when I go to Japan, but I don't know where I can study it at.
来年の３月に行くで、三ヶ月もいるので(永住まで延長したい）、色んな健康にいいことを勉強したいと思っています。
東京に住んでるアメリカ人の友達の家に泊まるつもりです。
できれば、東京にある薬膳料理教室があったら紹介してほしいです。
I'm planning on staying in Japan for 3 months(I want to stay forever), and want to study many health related things. I'm staying at a friends house in Tokyo, so it would be cool if you told me about any yakuzen-cooking classes in Tokyo.

因みに僕はアメリカのグルテンフリーとオーガニック料理に詳しいですので、日本でコックや斬新的な料理を作る人として活躍したいです。仕事でこれができる方法も教えてくださると嬉しいです！
ありがとうございます！
よろしくお願いします。
By the way, I'm knowledgeable about gluten-free and organic cooking, so I would like to be an organic cook in Japan or make novel food items. I would really appreciate it if someone could tell me how I could do this as a job in Japan too.
Thank you so much.

If you want to work as a chef in Japan, you would need to have attended cooking training school (credential) and have good professional experience already, and must find a restaurant who is interested in hiring you as one.

To study "yakuzen ryori," you might want to inquire with places like this:

This is one school that teaches "yakuzen ryori" in Nakano, Tokyo, and is registered with this association, which also qualifies "yakuzen" chefs:
