I think it can be highly beneficial for several reasons. Two of them are.
1) The first is the difference in the meaning of some words that somebody may find it beneficial for a better understanding. For example in Japanese the term uke which some may translate it as blocking it actually means receiving. Even a total beginner can benefit from this small information from the start. You can receive the attack by hitting first, move in a way that you bring the force of the opponent against him, take him of balance, block with a strike, or deflect the attack . This of course requires just the words that are used in the art and their meaning.
2) The second is that many people may want to train in their martial art's country of origin at some point. If they are well of economically, then they may go and do it for a few years. There are many Westerners that they went to Japan to study for 3-4 years or more and came back.
The second it is not the easiest task in the world though, since the Cantonese for example, have signs for letters. So for a Westerner, it can be more difficult to learn Cantonese rather than another Western language, as for example Spanish. For a Chinese it can be also more difficult to learn Italian lets say rather than Japanese for the same reason. And this is just one of the many differences.
Also for the second the differences in culture can be vast.!! Some Japanese for example when they offer you something, they do not take a no thanks for an answer, they consider it an insult. Many of the ways that you may encounter in some places in the orients, for a Westerner can be considered as totally slavish and unacceptable.
It is a different thing just to bow a bit, as a sign for respect and cultural aspect of your art and is a different thing to be in a place where (in certain places of course and not all) things like hierarchy and discipline are to the point and form of suppression. (Some in the west speak about discipline having in mind to get up form the bed or from the couch to go and do something. We all can understand that but imagine to be in a place where discipline means to go and sing in a Karaoke after 12 hours of work because the boss says so...Lol!!!)
Personally I am an advocate of the western liberal culture of innovation and being cool on things and I consider it important to be as free as it gets. Also I do not consider and I can not accept anybody to be above or under me in any type of way as most of us. Of course I can blend with oriental people and I did it many times but I wouldn't go and work for the average corporation in lets say....South Korea if you know what I mean. So for the second it may need even some further preparation. Lol!!
Nice question I added the extra information to give a better understanding for the second reason:) I haven't live in the orients, all the information that I am giving, is coming directly from the descriptions of many orientals that I have met, feel free to disagree.
