William Disclaimer: I used to work at the original Disneyland in Anaheim, California. JR Kyushu has announced that they will operate what they call the “JR Kyushu WAKU WAKU SMILE Shinkansen” from the 24th mid-December, during which select Shinkansen cars will be decorated with Disney characters. In addition, Disney music can be enjoyed via a QR code. FYI, a major Shinkansen yard 熊本総合車両所（くまもとそうごうしゃりょうしょ）is located in Tomiai Machi. If you’re passing by, it’s kinda cool to see those beasts lined up at rest. Video at link: https://kumanichi.com/articles/1149799
