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 house or the Tokugawa shogunate, thus strengthening the Meiji government's claims to the islands. Ijichi also penned a volume called Okinawa shi (Ryûkyû shi) (沖縄志（琉球志）), published in 1877.
