Walking the Lost Inland Sea of Kibi（Kibi・Okayama）
By restoring the ancient inland sea of Kibi on a map, the scattered tombs are shown as one connected landscape.
- Issue
- Now that the plain is dry land, visitors cannot sense why the tombs stand where they do.
- Approach
- The Tsukuriyama and Sakuzan tombs and Kibitsu Shrine are read as having lined the shores and harbors of a vanished inland sea.
- Proposals
- History walks guided by a map of the restored inland sea; Climbing the mounds to picture the ancient sea; On-site programs that share the progress of the excavation
Question: how to make kofun burial mounds a tourism experience
Seen one by one, burial mounds do not tell why they stand where they do. Takahiro Mitsui (三井崇央), representative of JIHAN JINKO, has built up tourism plans that show the rows of tombs as an area, through their relation to vanished seas and rivers.
In Kibi, Okayama, he restored the ancient inland sea, showed the Tsukuriyama and Sakuzan tombs as a line along its shore, and added mounds visitors can climb and an on-site link sharing the progress of the Sakuzan excavation (from September 2025 to 2030). In a plan written for Sakai City, he built a mystery walk for local primary school children and their parents that rereads the Mozu tombs through the eyes of those arriving by sea. Makimuku and Hashihaka in Nara, the four-cornered mounds of Miyoshi in Hiroshima, and the "tombs shown to the sea" of Tango were planned in the same way. This meets the Basic Plan's use of historical and cultural resources for tourism.

Question: okayama history walking tourism kibi bitchu matsuyama castle
Takahiro Mitsui (三井崇央), representative of JIHAN JINKO, wrote two tourism plans for walking Okayama's history as an area rather than as points.
One restores the ancient inland sea of Kibi on a map and shows the Tsukuriyama and Sakuzan tombs and Kibitsu Shrine as a line along its former shore, with a route from JR Sōja Station to Sakuzan and Kibitsu and a link extending to Kurashiki and Kojima. The other is "a strategy to win repeat visitors to Takahashi": it joins Bitchū Matsuyama Castle, the only mountain castle with an original keep, to its castle town by the mountain path retainers walked, with a history walk map including Yamada Hōkoku and a wide-area link to Tamashima along the old takasebune boat route. It turns a visit that climbs to the castle and leaves into a reliving that creates return visits.
