Miyako-kun embodies the Kyoto Municipal Subway system as its official mascot character. This anthropomorphic figure takes the form of a mole-like creature inspired by the Tozai Line's '50 series' rolling stock, distinguished by a conductor's hat symbolizing subway service. Miyako-kun actively promotes public transportation usage and guides tourism navigation across Kyoto. The mascot frequently partners with Kyo-chan, representing the Kyoto City Bus, appearing together on promotional posters and travel information materials. Both mascot names incorporate terms meaning "capital," a direct nod to Kyoto's millennium-long history as Japan's imperial capital. Miyako-kun participates in campaigns encouraging subway ridership within broader transportation initiatives.
