Japan is one of the most organised, surprising countries you'll visit. Ancient temples sit beside glass skyscrapers; ramen shops operate out of basement holes in the wall with Michelin-level precision; bullet trains run to the minute across hundreds of kilometres. Kyoto alone holds more UNESCO World Heritage Sites than most countries.
