Official meteorological observations in Japan started in 1872. Prior to that period,from 1700 onward until 1868, daily visual weather reports are documented in diaries at many places in Japan. In this study, we have recovered instrumental observations from Dejima (Nagasaki), taken under the responsibility of the Dutch, covering the periods 1819-1828, 1845-1858 and 1871-1878. The Dejima series overlaps by six months with the modern Nagasaki Observatory series 1878-present and overlaps in its pre-1871 part with the Nagasaki 1700-1868 documentary series. The recovered data provide a means for calibrating the documentary series and extend the start of the instrumental Nagasaki series back from 1878 to 1819, leaving major gaps during 1829-1844 and 1859-1871.Our final objective for this study is to reconstruct the 300 years temperature variations based on both instrumental data and diary weather records. As an example, we reconstructed a January mean temperature series at Nagasaki since 1700. The result shows the existence of apparent warmer period in 18th century compared to 19th century. Further investigations would be expected to clarify the overall feature of the climatic variations in Japan for the last 300 years.

日本的官方气象观察始于1872年。从1700年到1868年，日本许多地方记录了每日视觉天气报告。在这项研究中，我们从Dejima（长崎）的责任中收回了工具观察结果，涵盖了1819-1828、1845-1858和1871-1878时期。 Dejima系列在1878年至1871年之前与Nagasaki 1700-1868纪录片系列中的现代长崎纪念碑系列和重叠重叠六个月重叠。恢复的数据提供了一种校准纪录片系列的手段，并从1878年至1819年扩展了仪器的长崎系列的开始，在1829-1844和1859-1871期间留下了主要差距。这项研究的最终目标是重建基于工具数据和Diary Diary Veather Records 300年的温度变化。例如，我们自1700年以来在长崎重建了一月的平均温度系列。结果表明，与19世纪相比，18世纪的明显温暖时期存在。预计进一步的调查将阐明过去300年来日本气候变化的总体特征。
