The Idojiri Archaeological Musuem that is located at the foot of Yatsugatake Mountains in Nagano, Japan is well known for the excellent collections of Jomon Potteries of about 5,000 years B.P. And till today the research has been continued to ascertain the view of the world of those days based on the study of Jomon Farming and Earthenware Iconography. At the Idojiri Archaeological Museum, we have been creating an image database of those potteries since 1996. And, at this time, we decided to publish a series of catalog for each ruins in the manner of Publishing On Demand toward the world. This catalog is the Vol.1 and contains 10 masterpieces of Jomon potteries excavated in Tounai ruins and registered as National Important Cultural Properties. The commentaries on each potteries and excavation sites were written and compiled based on the report "Tounai, the center of prehistoric philosophy" that was published in 2011. As for the photos, we selected at least three photos for each pottery from the multi-view photos that were shot for creating the image database and laid out one photo by one page. The contents are as shown below.

Gutta percha, the trans-1,4-polyisoprene of botanical origin, was once the exclusive material for a variety of objects, such as insulative covering of submarine cables, chemical-resistant devices, golf balls, and denture and dent fillers. This book traces the 'journey' of this unique polymer which played a role as precursor to the synthetic thermoplastics emergence in 20th century. (The appendices briefly review the history of Xylonite (Celluloid) and Amber & Copal is briefly reviewed). 植物由来のトランス-1,4-ポリイソプレンであるグッタパーチャは，かつて海底ケーブルの絶縁被覆，耐薬品性装置，ゴルフボール，義歯・歯科用フィラーなどの為の唯一無二の材料であった。本書は20世紀に出現した合成熱可塑性プラスチックの前身としての役割を果たしたこのユニークなポリマーの「旅」を辿る（付章ではザイロナイト（セルロイド）並びに琥珀及びコパルの歴史を簡単に振返る）。ContentsForeword by Prof. Malcolm M.
