Niseko · 二世谷 · Hokkaido

A mountain town, an operating base, and a home.

Niseko is where we live, build, host, and think long-term. The 1898 Niseko hotel, Ando Village, Niseko Riverside, and a six-venue F&B portfolio — anchored in Kutchan, Hokkaido since 2007.

“Quietly, carefully.” Our founding posture — for the hotel, for Niseko, for every choice in between.

Ando Village is AI.D Japan's next Niseko anchor — twelve bespoke villas and a 1,000 sqm wellness clubhouse, designed by Tadao Ando Architect & Associates. The site sits twelve minutes from the 1898, framed against Mount Yotei.

Design Services Agreement signed September 2025. Concrete, water, and natural light — Ando's first large-scale residential commission in Hokkaido. Construction begins late 2026.

Seasons · 四季 · Four reasons to return

Niseko is not a winter destination. It is a year.

Winter in Niseko

Winter

Niseko powder. December through March — heated ski lockers, concierge transfers to Grand Hirafu and Hanazono lifts, and a butler-run private onsen in every suite.

Spring in Niseko

Spring

The locals' season. Bluebird skies, freshly groomed corduroy, and a deep base that holds well into April — at more than 50% off peak-winter rates. Fewer crowds, longer days, and the same powder mountain.

Summer in Niseko

Summer

Hanabi nights. Niseko's summer fireworks light up the valley after dusk. Cloud-forest walks on Mount Yotei, cycling routes along the Shiribetsu river, and open-air dining that turns the 1898 into a summer seikatsu destination.

Autumn in Niseko

Autumn

Mount Yotei in maple fire — the cone framed by golden grasses and red foliage. Wagyu menus at Tsubaki Bettei, sushi omakase by a visiting Tokyo chef. The quietest — and some say the most beautiful — season to visit.
