We've saved the best for last; everyone loves a ski holiday but they rarely come and go without leaving a conspicuous dent on the wallet. You can reduce that dent to a barely-discernible dimple if you're a savvy traveller who is happy to forego guaranteed powder (and the associated crowds!), in favour of sunny days on the snow and a whole lot of extra Yen in your pocket saved from the shoulder season discounts on accommodations, rentals, lessons, and more!
The most sought-after accommodations with easy chairlift access, stunning Mt Yotei Views, and attractive amenities such as onsen, spa, restaurants, grocer, etc are more readily available during spring, and usually at discounted rates.
6. We Actually Have Snow...

Yeahhhhhhhhh that snow you've been chasing around the rest of the world (and struggling to find), it's here in Niseko. While it seems the rest of the world has had super average snowfall, Niseko continues to dump.
Meaning, it's going to be a pretty epic spring.
