If you¡¯re nostalgic for the idea of a monoculture, then Japan is currently the place to be. In recent months the country has been unified by a shared enthusiasm for the film ¡°Demon Slayer: Kimetsu no Yaiba Infinity Castle,¡± the Osaka Expo and the continued on-field achievements of baseball player Shohei Ohtani.
