Can I buy the JR Pass 'over the counter' in Japan (in 2024)? Please confirm and help!

Hi,

I've just received words from my work-mates in Australia that tourists can no longer walk into an office in Japan,
to make the decision (while still inside the office).. whether or not.. to buy the JR PASS (or others) on the spot!

I hope this is NOT true because I am arriving in Tokyo (Haneda Airport) in about 7-days time,
and I am thinking of visiting multiple cities within Japan by trains.

If I (tourist) am allowed to buy the JR PASS from an office in Japan (not via 'online'), let me know these locations
where I can just walk in, make a decision (which JR PASS), and then buy it/them on the spot.

Many many thanks in advance
