One night isn’t enough when staying at Twin-Line Hotel Karuizawa. This boutique-style stay strikes the perfect balance between modern design and thoughtful comfort. Let’s talk rooms. Modern, spotless, and more stylish in person than they look online. Each room includes a desk, flatscreen TV, and a private bathroom with premium amenities, like bath salts and high-quality toiletries.

But what really makes the experience pop is the extras: complimentary drinks and snacks, a cozy fireplace lounge, and a rental selection with everything from foot massagers to beauty tools. They even lend out bikes.

The restaurant is Spanish-inspired and serves beautifully plated dishes for dinner. Breakfast offers a mix of European and Japanese favorites. Vegetarian options are limited, but the staff goes out of their way to help where they can.

They host a free-flow snack and drink session every evening from 9:15 to 10:30 p.m. It’s a guest favorite and a great chance to unwind or meet other travelers.
