I developed a friendship with a Japanese businessman while we were waiting to checking for a flight from Singapore to Tokyo. I invited him to the lounge after check-in. He thanked me profusely, "for inviting him to the VIP lounge". Since then, he has been asking me to visit Japan. When he changed jobs and relocated to another part of Japan, he sent me his new contact information and renewed his invitation.

I finally decided to go. He booked a hotel for me, after ascertainign what my budget was. As I am looking for a job, I casually mentioned if he knew of any possibilities for me. He said he would make appointments, not for "job hunting", but for greeting/introduction with a few companies. In the usual Japanese manner of efficiency, he has made up a schedule for me, that includes visits to near by cities on the weekend, and visits to restaurants and other sights at night. He will meet me at the airport and escort me to my hotel, despite my insistence that it was not necessary.

I am overwhelmed by his hospitality. I am at a loss as to how I should reciprocate. Since I have been out of a job for a while, I was not looking to spend lots of money on this trip. But I can;t let him pick up the tab every time. If he insists on doing so, how do I express my appreciation? Is it appropriate for me to take gift(s) for him/his family or his friends (from other companies) to whom e will introduce me? I have never been to Japan nor have I ever been a recipient of such hospitality.

I am looking for ideas/suggestions, how I should act. What are my responsibilities?

Thanks in advance.
