藩

This character refers to feudal clans that were abolished in 1871 (Meiji 4) in favor of prefectures (廃藩置県), and thus were predecessors of the modern prefectures. As we know from 落, flowers and water drops each have their own way of falling. This character says that clans' location was decided in the way flowers, water drops and dice fall: at random.
