I wanted to provide this for anyone who cares.
This is a timeline of a recent passport renewal at the US Embassy in Tokyo.
11 January – mailed the renewal application with all documents using the Red LetterPack from JP Post.
12 January – JP Post reported that my application was delivered at 10 am
19 January- I received an email from the State Department at 1:00 pm that my application was received and being processed.
01 February – My application was approved, and they mailed my new passport to the US Embassy In Tokyo
7 February – The US Embassy in Tokyo received (they probably received it sooner) and mailed my new passport to me.
8 February – I received my passport, large book, and new gen.
Entire process took almost a month ✌️
