This is a strange take. In Japanese it’s literally a consonant cluster [ts], which is to say it’s literally a Japanese “t” followed by a Japanese “s”. The Japanese “t” and “s” are not exactly the same as English, but they’re close enough, and English has the same cluster in, say, the plural “mats” of “mat”.
What “tsunami” breaks in English is not really the sound, but instead just the fact that English doesn’t allow [ts] unless it’s preceeded by a vowel.
It’s not at all like the T sound in Japanese followed by the S sound. The normal T sound in Japanese is pronounced by putting your tongue behind your top teeth and flicking your tongue down a bit. Tsu on the other hand starts with your tongue below your top teeth, and your cheeks pulled together a bit.

It’s also nothing like the TS in Mats in english.
Where are you getting this information? This “pull your cheeks together a bit” sounds completely out of left field to me.
