Trivia

 * Yuya is in the Wii Sports Club artwork covers, as a boxer.
 * His Japanese name is the same as his English name.
 * Yuya was featured in a Japanese promotional video for Streetpass Mii Plaza. In it, he states he is from Kanagawa, Japan, and has made a big mistake in his part-time job.
 * Strangely, Yuya poses as a boxer in Wii Sports Club promotions, but he's never seen in Boxing.
 * Also, in his box art, he has lighter skin.
 * He appears as a ghost in Mario Kart 8.
 * You can earn his badge for making an edit within an hour of a page's creation 100 times, so you need to be quick and active like for Gerald's badge.
 * You can also earn his badge for making 50 edits on "Baseball Teammates" articles, or for making 5 edits on Silver Badge Miis articles or for making 250 edits on Bronze Badge Miis articles.
 * Yuya also appears in a European guide for transferring Miis from the Wii to the 3DS. His appearance has been slightly simplified, however, as the Wii's Mii Channel does not have as many features.
 * He and Bo-Jia are the only Master Miis in Wii Party U to have a unique favorite color.
