Things to be aware of finding a job in Japan

I’m not sure where I can post this, but it’s more of a question on how to tell someone to stop coming to our workplace.

This guy (I believe American) has been coming by to more workplace asking for a job. The first time, he dropped off an obviously home-made business card but no resume. I‘m not knocking that he had home-made business cards, but they were really poorly done. He also looked more like a vagabond and reeked of cigarette smoke. Okay, I’m not trying to judge, but who goes into a place of business on a cold call without at least looking appropriate?

In any case, I thanked him for coming but told him we didn’t have any positions open.

He abruptly turned around and left.

Well, that was that, I thought, but I was wrong. He started to come in about once a month and each time we have all told him, no. Then, he started coming in when we have students around and he’s asking about a job and even interrupting us while we are busy with parents and their children.

My co-worker is so incredibly polite that she has never said anything other than no, but he has been coming for at least a year now, and it’s verging on creepy since that last few times we were not coy or anything and straight out told him to not come back. After the last time, we were very strong with out “No”, but he did say something under his breath about coming back later.

What will it take to have him stop? We’re reluctant to take it to an official level but we are worried that he might affect our business since he seems to come in at any time.

I guess it takes all sorts!
