Abstract: During the period of Nanbokucho, there were already particular tensous responsible for the affairs of Koufuku Temple, but at that time, the so-called “Nanto tensou” was only newly appointed tensous responsible for daily document affairs, which was updated and replaced with the promotion of official positions. This characteristic unchanged by the time Madenokouji Tsugufusa was promoted to tensou in 1376.When Tsugufusa was promoted to the position of gondainagon in 1383, it was customary for a newly appointed tensou to take over Koufuku Temple affairs,yet the long absence of a replacement suggested a significant shift in the characteristic of Nantotensou.During the Nanbokucho period,tensou was rarely directly involved in negotiations in gosous from temples and shrines.In fact,Tsugufusa did not actually intervene in Koufuku Temple affairs in 1379—1383,which was in line with previous practice.It was only the Koufuku Temple gosou in Kouryaku period that created the illusion in the Kennaiki that Tsugufusa was appointed as Nantotensou in Kouryaku period.Referring to the handling methods of the two gosou by Ouan and Kouryaku period, it can be seen that there was an authority gap between the Kuge, Bakufu, and Jisya after the reign of gokougon tennou, which cannot be simply understood as the shogunates absorption of Kuges power. Therefore, the year of 1383 was also an important watershed for the changes in the political landscape during the Muromachi era.
