Police certificate must be issued after you last lived in that country or territory?

Dears, I have an urgent question need to be answered, if anyone have the same situation or trouble as I have met. Please share your thought. Really appreciated! Here is the problem. I submitted my application on Feb and I visited Japan more than 6 months before, so according to CIC's request, I have to submit Japanese police certificate and I did so in April. Everything is fine so far. However, on July I was on a business trip in Japan again and I will go back to my home country in the end of August. According to CIC's website, the police certificate must be issued after you last lived in that country or territory. Since I visited Japan again. Do I need to updated my Japanese police certificate in Japan or after I leave Japan? Or I don't have to update it since when I submit it in April, it was issued after my last visit? Please, somebody help! Thank you so much!
