I’m working at a startup in Tokyo where I’ve signed an NDA some time after I joined. The NDA covers things like keeping all company information confidental and not joining a competitor for the period of one year.
Very recently, I have announced my resignation as I will join a different company. Suddenly, my current employer wants me to sign an NDA again which re-iterates over those same points I already signed, as if serving as a reminder not to break these rules.
Is this common in Japan? In the international community this seems to be a big NO, where everybody says NDA’s should have been signed before you join the company, and whatever you sign after can only be potentially bad. Is this something unique to Japan? I feel uncomfortable signing this NDA (I wonder, why on earth is this necessary?) and I was wondering if anyone who has had a similar experience could shed some light on this topic.
