Looking for alternative fuel in Japan

Hi, I'm looking for some alternative fuel for fire twirling instead of using Kerosene.

As our fire spinning community gets bigger n bigger every year, and especially we have high fire restriction law compare to other coutry, it'll be necessary to find out safer fuel which can be found in Japan.

I know most of fire people in Australia tend to use d60 or Firesol not really using kerosene.

I've benn looking for those type of fuel everywhere but can't find suitable one...

closest fuel we have to d60 or firesol is called"Wolfard Lamp Oil(for inside)", and we use them for inside fire performance.
but it costs like over $10 per 500ml (Price of kerosene is around 60c per Litter in Japan) so that's too expensive.

I'm sure soon or later people or society here in japan will start recognize how bad kerosene is, because it's most likely our culture stance.
and worst case I'm so afraid "dangerous act" such as fire twirling will be banned...
cannot let it happen..

Also we are very much keen to provide safer fuel in Japan Fire Festival too.
I personally don't want to use kerosene for such big fire festival.

Anyone have suggestion??
Any safer fuel(and hopefully not too expensive) that can be found in Japan too?

Thanks a lot!!

I was under the impression that Kerosine (paraffin) was the safest fuel you could get, and other things (such as tiki fuel or lamp oil) where just kerosine with additives to make it easier to light and less smokey. What's so bad about kero?
