Highlights:

Central Kinki areas of western Japan are one of the areas where the Neogene and Quaternary paleobotany and stratigraphy in Japan have been most well-studied. Plant macrofossil collections in the Osaka Museum of Natural History including Professor Shigeru Miki’s collection give an overview of floral changes in Japan since the Neogene. The Middle Pliocene sediments of the Kobiwako Group in Iga Ueno reveals a paleo-ecosystem of the first stage of an ancient lake leading to modern Lake Biwa with plant and molluscan fossils and elephant footprints. We can see the Early Miocene marine sediments of the Awa Group yielding fossil whales, molluscs and leaf fossils. On the third day, we will visit a stand of Sciadopitys verticillata near the peak of Mt. Odaigagara (1,694 m) and see the modern habitat of the endemic tree. The mixed conifer-broadleaved forest along the hiking route is a cool temperate cloud forest dominated by Fagus crenata, Chamaecyparis obtusa, Abies homolepis, etc. Nara City is an ancient capital city established in AD 710 and listed as a UNESCO World Heritage Site for the historic monuments and a primeval forest of Mt. Kasuga. The primeval forest bordering Nara city is an evergreen broadleaved forest protected religiously for a long time. Here a climax forest dominated by Quercus subgen. Cyclobalanopsis, Castanopsis, and Lauraceae can be observed.
