Field notes
Combined with Imashiroduka Kofun (id:60), bus from JR Takatsuki or Hankyu Takatsuki-shi Station is convenient. The Takatsuki City Imashiroduka Ancient History Museum (adjacent to Imashiroduka) provides an overview of Takatsuki-area kofun culture. Located in hilly terrain — hiking-appropriate footwear is recommended.
