Usage of -san in English emails


Working in a Japanese based company I often see that in written English which
is (directly or indirectly) addressed to Japanese the suffix -san is attached
to names.

With some basic knowledge of Japanese I have some understanding how -さん is
used in Japanese. Having in mind that it would seem unnatural for me to
encounter Herr Müller instead of Mr. Müller in an English text I am wondering
how natural it is for a Japanese to see -san being used in an English
conversation a) attached to a (romanized) Japanese name or b) attached to an
English/German/... name.

I hope this question will not be marked as opinion-based because I am actually
interested in a general answer to help improve my conversation with Japanese
people.




San is often used in informal e-mail. San or Kun is maybe good to show
friendliness. This depends on the custom of the organization.For me, it seems
a little strange. I always feel why you suddenly use Japanese in English
email?. In my mind,it sounds like the foreign people's unnatural
pronunciation.
