in a similar question below, this tool is probably the safest third party app, if not tied with using stand-alone flash player.

using API link (regardless of what app you are using) since we're outside JP is all in itself illegal. the only way that they could detect you is filtering IPs outside of japan (already in networking side) which is outside the bounds of this tool nor any third-party app.

as previously mentioned as well, if this isn't safe, no other third-party app is safe.
