Japanese · Pronunciation Guide
ku-ni, two short beats — flat lips on the u and a palatalised n.
kuni
Nothing is promoted here: two units of the same length, and standard speech leaves the word unaccented — the pitch rises from ku to ni and stays there, so a following particle sits high. Neither beat should be heard as the word's centre.

日本は美しい国です places 国 after 美しい, whose long final i runs for two beats. That gives you a sustained vowel colliding directly with a short one, and the join must not blur — the adjective's length belongs to the adjective, not to the noun.
"KOO-nee" rounds the u, stresses the first beat, and stretches the final vowel to English length. Spread the lips, level the two beats, and halve the i. The palatal n is the subtler point: tapping with the tongue tip gives an English n, where Japanese uses a broad, flat contact.
