According to a certain source, Isora offered his navigational services in "exchange for a sexual relationship" with the empress.[15] Though "the motif of divine union between Jingu and a sea god is relatively uncommon", the notion that Azumi-no-isora obtained sexual favors from the empress is attested in shrine-foundation myth (jisha engi [ja]) document called the Rokugō kaizan Ninmmon daibosatsu hongi (六郷開山仁聞大菩薩本紀).[16] Other shrines of the cult do not promote this idea. Isora carries out the task "without any sexual compensation" in the Hachiman gudōkun [ja] attributed to a priest at the Iwashimizu Hachimangu.[17]
