富竹 ジロウ

He visits Hinamizawa about three times every year and is known by the villagers. Tomitake also seems to know a lot about the village and its history, although this may be in part due to his relationship with his girlfriend Takano Miyo, who has a deep interest in the subject. It is unclear whether "Tomitake Jirō" is his real name, or simply an alias to complement his false image of a harmless photographer (as suspected by Furude Rika in Minagoroshi-hen). In the first game, Onikakushi-hen, the Investigation Memo TIP notes that "Tomitake Jirō" is only his pen-name.[From Higurashi Wiki]
