Itchō began his career training in the formal Kanō school style. He soon rejected its rigid conventions to focus on the daily lives of common people in Edo. His work combines classical ink techniques with the observational wit of ukiyo-e. Paintings like Taking Shelter from the Rain and Bugaku Dances show his interest in human movement. He used humour and irony to depict street scenes and religious figures like Jizō Bosatsu.

Modern collectors value Itchō for his ability to capture character through minimal brushwork. His work often leaves space for the viewer to breathe, making it suitable for contemporary interiors. He applied his style to both large screens and small, functional items like inrō cases. This range makes his work accessible for different types of display.
