Bikaben san, I can kind of empathize with you--I have been in those shoes once before. . . to a degree. Again, I do hope things go in the best line of probable outcome that they potentially have, for you.
Now as regards my question in the PM I had sent you this past Friday morning, I feel let down, that you refused to answer. At any rate, your most recent post in this thread, also proves that this thread has not only already served its purpose, but has lost its right to be held related to working in Japan.
For the above reasons, your refusal to answer to my PM included, I am closing this thread until further reason to re-open it. Now, as Mike has suggested, once you do make solid plans to come here, have everything pretty much lined up, ticket in hand or in the final planning stages, or most near it, please do start a thread with any real and immediate questions that you may have, AFTER having done some research first !!
And with that, this thread is closed until further notice. Sorry for any inconveniences, and thanks to those who have participated. Mars Man
