Head-to-body ratio
The proportion of head size to body length is the most concise indicator of regional origin and an artisan's hand.
- Naruko and Togatta have large heads and a dignified upright stance.
- Tsuchiyu and Nakanosawa have small heads and long bodies — an elegant proportion.
- Yajiro has an extremely large head, with characteristic lathe-turned lines like a beret.
