While he doesn't typically use a bow and arrow, he does wield a zanpakuto, a soul-cutting sword, which takes the form of a bow when he uses its shikai form, called Tensa Zangetsu.
Here's why you might be confused:
* Zanpakuto forms: Many zanpakuto have unique forms, some resembling weapons other than swords, like bows, chains, or even animals.
* Artistic interpretations: Artwork or promotional materials might depict Ichigo with his zanpakuto in its bow form, making you think he uses it regularly.
