It's such a shame the Japanese culture doesn't want to face a discussion and "force" Kamakura onto the list due to the negative feedback from ICOMOS. Everything goes nowadays.
Indeed. Kamakura is quite lovely! Some of the most athmospheric temples I've visited (and that's saying a lot, considering most Japanese temples have a certain vibe).
Tokyo Tower lol when I was a teenager I watched a few Japanese shows and couples would literally meet up at the tower at least once per show. That's modern OUV!
Tokyo Tower would indeed be a quite ridiculous addition to the WHL, but Tokyo does have some quite unique examples of modern architecture: The Yoyogi National Gymnasium (by Kenzo Tange, built for the 1964 Olympics), the metabolist Nakagin Capsule Tower (which is threatened with demolition) and Shizuoka Press and Broadcasting Tower, some of the luxury brand buildings in Ginza and Omotesando (e.g. Mikimoto building by Toyo Ito, Prada Aoyama building by Herzog & de Meuron, Tod's Omotesando building also by Toyo Ito, C Dior building by SANAA).
