don't get me wrong, I'm taught well. But as a brit living in England with English instructors who teach in English, sometimes I don't think we fully articulate the essence of the art, which is Japanese culturally and historically.
Understood. Fortunately, it's not a barrier if there's underlying passion for and understanding of the subject matter.
There are Hakkoryu folks in the U.S., for example, who travel to Japan to train, even if a special event/training is not being hosted in Saitama. Fortunately, there are some quite accomplished teachers in the U.S. who are quite versed in Hakkoryu's internal aspects: and those are the folks who are ardent shiatsu practitioners.
