Meteorological Service in Japan. 



At present there are, besides the Central Meteorological Obser- 

 vatory, Tokyo, 63 Local Meteorological Observatories Avhich are connected 

 with each other, and which are limited by the jiolitical divisions. 

 The Tokyo Observatory is the Central Bureau of the Japanese Meteo- 

 rological Service. All the local observatories make meteorological and 

 seismological observations according to instructions issued by the Central 

 Bureau. All the instruments in use in these local observatories are 

 of the same type and quality. They are carefully examined and 

 tested in the Central Observatory, Tokyo, and their instrumental 

 corrections are determined before they are distributed to the local 

 observatories. The hours of observations and methods of making the 

 observations are the same in all the observatories except that some of 

 them make six-daily observations and others hourly observations. All 

 of them send their meteorological returns to the Tokyo observatory and 

 the results of the observations are published in extenso in the Monthly 

 and Annual Keports of the Central Meteorological Observatory. 



The local meteorological observatories belong to the prefectures 

 into Avhich Japan is divided for administrative purposes. There is at 

 least one observatory in each prefecture so that there are at present 63 

 observatories. In each prefecture there are many raingauge stations 

 and climatological stations. These stations arc under the direct control 

 of the meteorological observatory of the prefecture concerned. In 1926 

 there are about 1600 of them in Japan, including Korea, Formosa 

 and Ivarafuto. 



The results of these observations are published in the monthly 

 and annual reports of the local observatories. They are also reported 

 to the Central Observatory through the local observatories. The rain- 

 fall data are published iu the "Rainfall" of Japan. 



Besides these government observatories, there are a few private 

 meteorological observatories. There are also the Imperial Mariue 

 Observatory at Kobe, and the Aerological Observatory at Tateno near 

 Tsuchiura. Both are Government institutions independent of the 

 Central Observatory, Tokyo.
