New US iPhone ok for Japan?

According to Apple, the iPhone 8 Plus model numbers that work in the US are...
Model A1897
Model A1864 (GSM)
Model A1864 (CDMA)

The iPhone 8 Plus model number that works in Japan is...
Model A1898

Does that mean the iPhone 8 Plus model numbers from the US will not work in Japan?

Three years ago I went to Japan with an unlocked iPhone 6 from Apple.
I specifically told the sales clerk at Apple I needed the model number that works in Japan (A1586).
He gave me that model number.
When I went to Japan, Docomo gave me a SIM card and a contract.

I want to do the same with my new unlocked iPhone 8 Plus, but the model number is NOT the one that works in Japan (Model A1898).

Will it not work?

use apples site to check supported bands.

I did that.

Apple lists different models for each country.
As well as different bands.

whether it's a different model, the bands do overlap, check if the us model have the bands that the Japanese model have.

Iphones work everywhere.

Speaking from experience in US, Japan, Europe, Asia other places.
