I am looking for basic Professional Indemnity Insurance coverage up to 10Mil JPY cover.

Casual side work, independent of current employer. I do not have a registered business here anymore.

Any suggestions?

I found it incredibly cheap here, at least compared to the uk where i have previous experience.

Has anyone tried this one for PI insurance, and if so is this an acceptable PI insurance for freelancing?
