Japanese · Pronunciation Guide
se-n, two beats, ending on a full count of nasal hum rather than a clipped English n.
sen
Two morae, of which one is voiceless of any vowel. Compare it directly with 三 (san) and 四 (yon): all three are vowel-plus-ん, all three are two beats, and in all three the second beat is pure hum. Once that pattern clicks, a whole family of Japanese words stops sounding rushed.

この本は千円でした builds 千円 (se-n-e-n), which is genuinely awkward at speed because a moraic ん is followed immediately by a vowel. Native speakers keep them apart — the ん stays a distinct nasal beat and does not simply become the n of a following "nen." Say se-n-e-n as four honest counts.
English speakers produce "sen" as a single syllable of the same length as the English word, cutting the nasal to a closure rather than a beat. In compounds this compounds: 千円 collapses into two syllables, "sen-en," losing half the word's length. Hold the nasal, and keep the e short and pure so it doesn't drift toward an English diphthong.
