You could cover a lot of ground on a trip to Japan, or very little, and still get to experience the best of what the country has to offer. Centrally located Kansai, has it all: not just Kyoto, but also a vibrant city in Osaka, plus fantastic hiking and hot springs.
A deep dive of this region works well for first-time visitors, and repeat ones who want to take things slower. You’ll get to really engage with Japan’s ancient culture, and get a mix of famous destinations and ones not yet firmly on the tourist map. Two weeks is ideal, but 10 days works in a pinch.
