Ten days is the sweet spot for a first visit; seven is the practical minimum; fourteen is where Japan stops feeling rushed. The number that matters is not days but bases — each change of city costs you roughly half a day. Seven days means two bases. Ten means three. Fourteen means four. Adding a fifth city to a ten-day trip does not add a city; it removes a day and a half.
The rule that decides everything: bases, not days
A "base" is somewhere you sleep more than one night. Every time you change base you lose the morning to packing and checking out, the middle of the day to travelling, and the evening to finding your bearings. Call it half a day, honestly, each time.
So the real arithmetic of a Japan trip is not how many days do I have but how many half-days am I willing to spend moving.
| Trip length | Bases | What genuinely fits |
|---|---|---|
| 5–6 days | 1 | Tokyo only, or Kyoto only, with day trips. Do not try both. |
| 7 days | 2 | Tokyo and Kyoto. Osaka as an evening, not a base. |
| 10 days | 3 | Tokyo, the mountains, Kyoto. Nara and Osaka as day trips. |
| 14 days | 4 | Add Osaka properly, or go west to Hiroshima. |
| 21 days | 5–6 | Add Kanazawa, the Seto Inland Sea, or Hokkaido. |
Five or six days
Short, and perfectly good — if you pick one city. Tokyo with a day in Kamakura or Nikko is an excellent short trip. So is Kyoto with Nara and Osaka as day trips.
What does not work is Tokyo and Kyoto in five days. You will spend one of those days on the Shinkansen and arrive in each city just as you were beginning to understand it.
Seven days
The most common length, and the one that most often gets overloaded. Seven days is four nights in Tokyo and three in Kyoto, or the reverse. That is it.
Osaka is fifteen minutes from Kyoto, so it belongs as a long evening rather than a base. Hakone in seven days is possible but costs you a third of the trip in movement — I would usually leave it.
Ten days — the sweet spot
If you can take ten days, take ten. It is the first length where you can add the mountains without cutting into the cities: four nights Tokyo, two in Hakone or the Fuji Five Lakes, four in Kyoto.
Ten days also gives you one genuinely open day in each city, which is consistently where people's favourite hours end up.
Fourteen days
Two weeks is where Japan stops feeling like a checklist. The same three bases as ten days, plus either Osaka properly or a run west to Hiroshima and Miyajima — and a third of the days deliberately left empty.
The full version of this is set out in our 14-day itinerary.
Three weeks or more
Now you can afford somewhere that is not on the main line: Kanazawa, the Nakasendo villages, the Seto Inland Sea art islands, or Hokkaido. This is also the point at which flying domestically starts to make sense rather than taking the train everywhere.
The mistake at every length
It is always the same one: counting cities instead of counting mornings. An itinerary with six cities in ten days reads as ambitious and travels as exhausting, because six cities means five moves, which is two and a half days gone before you have seen anything.
If you take one thing from this: decide your number of bases first, then fill them. Everything else in the plan follows from that.
