The following year (in 1873), Ijichi compiled a history of the Ryukyus' relationship with Japan, from antiquity to the present. Entitled Ryûkyû hôhan jiryaku (琉球封藩事略), it covers both the Ryukyuan missions to Edo and the kingdom's tributary relationship with China, but subtly emphasizes Ryûkyû's relationship with "Japan," rather than with the Shimazu or the Tokugawa shogunate, thus strengthening the Meiji government's claims to the islands.
