Analyzing OURAIMONO documents to research on the early modern dialect in Northern West Coast of Japan.

本研究显示，大来物语文献在东北地区的分布并不均匀，沿着的是文献学和文献学的介绍。研究结果还表明，这些文献在探讨近代早期青森、秋田、岩手、山形等地区的教育环境和社会文化背景方面发挥了重要作用。但最显著的结果是，这一时期西海岸地区的社会文化背景与中部地区不同，即西海岸地区受京都和大坂文化的影响较大，中部地区受江户文化的影响较大。

This research presented an uneven distribution of OURAIMONO documents in the Tohoku region along with its bibliographical and philological introduction. The results also demonstrated those documents played an important role in order to discuss the educational environment as well as socio-cultural settings in such regions as Aomori, Akita, Iwate and Yamagata during the early modern period. The most significant result, however, said that the west coastal area differed from the central area in terms of its socio-cultural settings in this period, that is to say, the coastal area was greatly influenced by cultures in Kyoto and Osaka, and the central area was affected by Edo respectively.
