- head-high (atamadaka): falls after mora 1
- flat (heiban)
How to read it: a line over a kana means the voice is high there, and ↓ marks where it drops. A kana with no line is low. With no ↓ the pitch stays high to the end and does not drop even on a following particle (が, は).
world, society, generation
Yo, “world”, is from Old Japanese, with a pronunciation distinct from 夜 (yo, “night”).
