Sensei Arti, as we call him, is an extraordinary human being. He is fluent in several languages. He lived in the US for years, so his English is superb. His superior intelligence, knowledge, passion and pride are evident through his teachings. We learned more in a couple of hours with him than in all the other days we spent in Japan with others. He is also a historical figure. He has global knowledge and vast experiences, which makes him the perfect companion and better tour guide.
