yeovan, skiing is an inherently dangerous sport, but I'm sure you're aware of the risks and take appropriate precautions, such as wearing a helmet. Just a reminder here: http://journals.worldnomads.com/safetyhub/story/71452/Italy/Ski-Safety-Tips-A-reminder
But I guess you're asking about the after-effects of the earthquake, tsunami and nuclear power plant malfunction? The Japanese government has designated a no-go zone 30 kilometres around the failed Fukushima Daichi power station. Some foreign governments recommend you don't go within 80 kilometres (except if you're passing by on the freeway - keep going don't stop).
Osaka is over 600 kilometres away. Niseko is 600 kms in the other direction.
The greatest safety risk is someone else's runaway ski!
