Yeah now that I think about it, the IPA director thing was a speculation on my part. You also brought up a good point that if he was from the same agency as glasses guy, the cabinmates wouldn't have felt the need to specifically name his agency.

He could've simply visited the IEA basement before going to the DC. But I agree we should wait for confirmation.

About my findings:

No real connection between the japanese ranks, not that it matters...

Now to the important stuff, I did some research on the RVA and IPA, and find out that the RVAs are most likely smaller departments inside the IPA or IEA

特別渡航課 (Restricted Voyage Agency, lit Special Voyage Department)

国際渡航許可庁 (IPA)

The 課 used in RVA is a smaller unit which means these 2 agencies are not the same thing (at least entirely). Furthermore, since it's a smaller unit, the RVAs should belong to the IPA or some other place (the IEA? since the glasses guys (the IEA Deputy Secretary) is the one coordinating the RVAs.)
