ta-i-yo-o, four beats — the ta and i are separate, and the final o runs long.
taiyou
Four beats: two short ones at the front and a long vowel filling the back half. English delivers this in two syllables, which halves it. Separate the opening vowels and then hold the closing o for a genuine double count.

今日は太陽が出ています opens with 今日 (kyo-o), itself a long vowel, so the sentence contains two held o's within a few words of each other. Between them, が and 出て are short and quick — a good demonstration of how Japanese alternates held and unheld beats.
"tie-YO" is the standard collapse: opening vowels fused, closing vowel shortened, and stress somewhere in the middle. That's two beats out of four. Pulse the ta and i apart, then hold the final o until it feels overlong — it probably still isn't.
