I'm quite scared every time I have to use NEMA plugs (I live in Japan).
Coming from europe, the bottom of the two connectors is insulated
This ensure that even if you touch them while plugging/unplugging, it will always be safe to touch.
Meanwhile with NEMA ones, there is no such insulation and I often see my appliance partially disconnected (but power still flowing) because of either the weight of the AC/DC or the cable has been pulled accidentally.
Am I right to be worried about accidentally touching the connectors, and what to do about it ?

Nothing is safe. There are only degrees of safety.
European plugs incorporate more safety features, which makes them safer. But they also work with higher voltages, which are slightly more dangerous (230 instead of 120 in US or 100 in Japan).
UK Plugs and outlets have many more safety features than any other design, so are safer still.
None of these designs can always prevent a determined or negligent person from electrocuting themselves.
I think it is better to regard them as less safe rather than unsafe, Just take extra care.
