Developing the aquatic connections, an early fourteenth-century account of itinerant monk Ikkō, the , written in 1328 by a monk at on the subject of the temple's founder, relates an episode involving Ikkō, Hachiman, the Dragon King, and a waniguchi. According to this text, when Ikkō was performing odori (dancing) nembutsu at Usa Hachimangū, Hachiman appeared and gave him a waniguchi. When Ikkō was subsequently journeying to Shikoku, the Dragon King manifested himself and requested Ikkō's gong. The sea rough, he obliged, casting it into the turbulent waters. When Ikkō reached Sanuki, a "blue-robed child" appeared from the sea, declaring that due to the merit earned Ikkō would be released from suffering and have his waniguchi returned to him. A tortoise then appeared bearing it in his mouth and returned the lost item to Ikkō. A "tortoise tooth gong" is still in the keeping of Renge-ji today.
