Umezu Masakage Diary - Umezu Masakage Diary

This diary was written by Umezu Masakage (1581-1633), a samurai of the Akita domain, and spans the period from 1612 (Keicho 17) to 1633 (Kan'ei 10). The 25 original volumes have been passed down through the Umezu family, but currently 24 volumes are in the possession of the Akita Public Archives, and the remaining volume (volume 16, part 2) is in the possession of the Senshu Bunko. This diary is Masakage's personal diary, and is not what is commonly called an official diary. However, as Masakage was a person who served as Yamabugyo (magistrate of the mountains) of the Innai silver mine, Soyamabugyo (magistrate of the finances), Karo (chief retainer), and so on, it contains many articles about the official affairs of the Akita domain. Most of the originals can be considered to have been written by Masakage himself, and are in good condition, making them valuable materials that provide concrete insights into the politics, economy, and society of the early Akita domain. They are included in the Dai Nihon Koroku (Records of Ancient Japan).

秋田藩士梅津政景（1581―1633）の1612年（慶長17）から33年（寛永10）にわたる日記。原本25冊は梅津家に伝えられてきたが、現在24冊は秋田公文書館、他の1冊（巻16下）は千秋(せんしゅう)文庫が所蔵している。この日記は政景個人の日記で、いわゆる公用日記ではない。しかし政景は院内(いんない)銀山の山奉行(やまぶぎょう)、惣(そう)山奉行、勘定奉行、家老などを歴任した人物だけに、秋田藩の公務に関する記事が多い。原本はほとんどが政景自筆とみてよく、保存状況も良好で、秋田藩初期の政治、経済、社会などが具体的にわかる貴重な資料である。『大日本古記録』に収められている。
