Meet Gerard & Sergi, the Founders of Yukiumi

Two skiers from Barcelona who came to Japan, got stuck, and built a backcountry home in Central Hokkaido.

Our story

From Barcelona to Kamikawa

Gerard and Sergi grew up in Barcelona with active, sporty lives in the mountains, and both worked as ski instructors. Gerard had just finished university and was travelling the world when the pandemic hit.

In 2020 the lockdowns made going back to Europe very difficult, and leaving Japan wasn't easy either. So they stayed. In Kamikawa, on the quiet north side of Daisetsuzan National Park, they started a small project for friends and riders who wanted to ski Hokkaido's deep snow. That project became Yukiumi Hokkaido, our main business today, with lodges in Kamikawa and Furano, a guide team, a bar and restaurant and a backcountry rental shop.

Co-founder & guide

Gerard Martinez

Gerard has been skiing since he was a small kid and raced in his younger years before becoming a ski instructor. He speaks six languages: Catalan, Spanish, Italian, Portuguese, English and Japanese, so most guests can talk to him in their own.

What we do now

Running Yukiumi, Still Guiding

Today we manage the whole company: our guide team, staff, lodges and every guest's trip. We still guide, mostly in the background: with returning guests who have skied with us before, and with riders who want something more challenging, from research days to exploration projects in terrain few people visit.

Why We Love Kamikawa

If we had to pick one area, it's Kamikawa. It's quieter, the quality of the snow is pretty much unbeatable, and it's where everything started for us.
