by the way; I also have another tricky idea, that is; While this operation, please inform to whom you talk that you knowing that this is the unusual approach, but this case widely affecting human rights of many japanese persons. Also, tell them that you longing for MPD to accept your damage notice of this case and the crime investigation would be started as soon as possible.
TO DO: First, call japanese embasee in manila. Then, tell who you are and things what you facing. also tell them that this is the human-right related critical matter that needs to be handled quickly to prevent further damage by abusing leaked data. (if needed) To make them believing that who actually you are, you might need to invite them to your office to show what's you're doing.
This will give you this case to be handled as one of inter-nation diplomatic matter. but i expect that the case handled appropriately.
