For details on the "Japan Knowledge School" version of "Rika Nenpyo," please visit the content information section on the official "Japan Knowledge School" website. Expectations for the New "Rika Nenpyo" We received comments of expectation for this new addition from Mr. Makoto Hirano, a librarian teacher and science teacher at Chuo University Affiliated Junior High School and High School. "Rika Nenpyo," which will celebrate its "100th volume" milestone next year, has finally been added to "Japan Knowledge School." As it is an essential reference book for school libraries, I had been eagerly awaiting the day it would be available on this service, which covers a wide range of reference books. For students, it will be a learning resource that they can easily access anytime from their devices, and for teachers, it will be a reliable teaching material. Although the title includes "Science," its applications are not limited to the scientific fields. For example, when analyzing the descriptive passages of literary works in a Japanese language class, calendar, astronomical, or meteorological data can be utilized. I have high expectations that the "Japan Knowledge School" version of "Rika Nenpyo" will be utilized in diverse ways in the field of school educatio
