紅葉
Fly into CTS. The ginkgo avenue at Hokkaido University, then Jozankei onsen in the hills. Two days.
90 minutes from Tokyo. Zenko-ji at dawn, Togakushi cedars in the afternoon, snow monkeys next morning.
Gaien ginkgo on foot, Rikugien lit up after dark. The city does autumn in gold.
Osaka Castle park in the morning, the Minoo Falls trail before sunset. Street food in between.
Tofukuji at opening time, Eikando by night. December, when the crowds thin and the maples burn.
Most people think Kyoto peaks in November. It doesn't.
Tokyo → Kyoto → Osaka? Nov 20 to Dec 12. All three in one trip? Land between Nov 20 and Dec 12; the 10-day covers it.

Prices checked September 8, 2026. We'll update this table, including if we stop being cheaper.
Strong signal in the cities and on the main rail lines. Deep mountain valleys can drop out.
One short email a week while you travel: the quiet gate, the queue worth joining, the last train home.
