All,

I need to make a 100KY furikomi while visiting Japan. Destination bank is UFJ. I'll be staying in Shinjuku. I have a US, chipped Schwab ATM card. My ability to speak Japanese is very low, and my ability to read Kanji is about that of a Japense 2nd or 3rd grader.

I seek advice on the easiest/simplest/most-likely-for-baka-gaijin-not-to-screw-it-up path.

Should I go to a UFJ ATM and try a card furikomi?

Should I get 100K cash from a 7-11 and then do a cash furikomi at a UFJ branch?

Some other combination?

Edit to Add: all the advice I can find on the internet and here is old enough that I am unsure that they still apply to current conditions. Would greatly welcome anyone with recent experience/advice.
