The real decision is which day most needs a complete group state

Kanas and Hemu are both major highlights, but they do not place the same kind of pressure on a first-time family route.

The stronger order usually follows the day that most needs breakfast discipline, transfer coordination and stable energy.

Kanas usually belongs earlier, before the route starts carrying rear-end fatigue

Kanas often behaves like the route's core mission day. If the group reaches it while still relatively fresh, execution usually improves.

That matters even more for mixed-age groups, where later mornings and slower resets tend to build over time.

Hemu later often helps the route slow down instead of tightening further

Hemu is still important, but it often works well as the segment that helps the group breathe after the heavier scenic push.

That can make the whole northern route feel more coherent instead of forcing the most demanding day into the back half.

Hemu first makes more sense only when the front-end pressure is already low

If arrival is early, the group is strong and the family intentionally wants a softer scenic warm-up, Hemu first can still work.

For most first-time mixed-age groups, though, protecting the core day first is usually the stronger default.
