学校: gakkô Renku is an evolving poetic form. In Japan of the 8th to 15th centuries, when its basic rules were established, renku didn't include education as an essential category of human experience. For renku poets of the 21st century, things are quite different. Schools of all types and levels—kindergartens, elementary schools, middle schools, high schools, colleges, universities, trade schools and so on—play an important role in human reality of modern times.
