Project Leader RIHN Professor Nakatsuka’s specialties are palaeoclimatology and isotope biogeochemistry.
First, we reconstruct past climate variations in Japan and Asia at annual or seasonal time resolutions for the last several millennia, using up-to-date palaeoclimatological methods to identify outstanding periods of climate variation.
Then we use historical and archaeological approaches to investigate how local societies reacted to climate variation in order to clarify common sociocultural characteristics of societies that are tolerant or vulnerable to changes in climate.
However, some past societies continued making efforts to overcome the influence of climate variations, while other societies collapsed.
Comparative evaluation of historical climate adaptations may allow us to explain Japanese history since the Jomon era as a sequence of societal transformations designed to overcome large intermittent climate variations.
Variation in the tree-ring cellulose oxygen isotope ratio is compared with that in master chronology to determine the matching year (c & d).
▲PAGE TOP So far, we have been using many tree-ring samples from around Japan in order to analyze tree-ring oxygen isotope ratios during the last 4300 years in annual time resolution.
The books use a frame narrative to split the story between present-day Kvothe (under the name of Kote) as a broken innkeeper, seemingly bereft of his powers and music, and the history of his life as he recounts how he got to that point.
Given that music plays such an important role as part of Kvothe’s character and the story, Miranda — coming off dual successes as composer-star of the mega-hit Broadway musical also notes that Miranda has an option to be involved in a possible future stage adaption as well.
First, Japan is located at northeastern rim of the Asian summer monsoon, where small changes in monsoon dynamics might have significantly affected rice paddy cultivation on which Japanese sustenance has historically depended.
Second, due to the historically high literacy rate and long-lasting family system in Japan, innumerable historical documents dating back to the 8th century are preserved in both private and governmental sectors.
As a result, we can understand how historical societies could or could not overcome serious climate changes in the past.
