A monument of townspeople astronomers in the Edo period

Original Text

Hazama Chogai was a townspeople astronomer in the Edo period. Currently, I use the solar calendar, but in the Edo period it was the lunar calendar. Therefore, the actual operation of the sky sun and the calendar were very different. At that time, it was important to know the weather because the collection of nengu by agriculture was the center of the economy. Although he was a townspeople, he had a direct visit from the Shogunate due to his excellent astronomical observation technology, but he refused this. However, I made astronomical observations in such a place ...

It is located in the square of the central separation zone.

Original Text

Mr. Managaya was a townspeople who ran a quality and merchant ... but at the time when the error between the calendar and the sun was terrible, the shogunate also started the calendar and Mr. Nagaya participated in this. I refused to invite the shogunate to be a shogunate, and instead received an observation instrument. However, on the day he carried out the observation, it seems that the area around Nagahori-dori was completely closed to the shogunate direct 々. It is located in the central separation zone, a little closer to Nishi Nagahori from the Nishi-Ohashi intersection of Nagahori Dori street.

遺構はありません。中央分離帯に碑と碑文だけ。

地下鉄・西大橋駅を出ると中央分離帯があり、そこが駐輪場になっていました。よくよく見るとその一角に碑がありました。ここも跡地に碑があるだけで、何の遺構もありませんでした。但し、碑の横に説明板が立っており、碑だけのポイントにしては充実しているとも云えます。
