After the Bingo Kokufu, Aki Kokufu, and Musashi Kokufu were promulgated, the cities where facilities like the modern prefectural office were set up during the Nara-Heian period are called Kokufu.If there is a relationship between them, I think that every country can be said to be a big city with noble people who came from the center.In addition, Emperor Shomu made each country build a seven-storied pagoda and enshrined the Golden Light Sutra, the sutra-copying sutra.In addition, Kokubunji Temple and Kokubunnanji Temple were ordered to be built, and it is reported that each country's prefecture obeyed them.
