A ryokan is a traditional Japanese inn featuring tatami-mat rooms, futon bedding, communal or private baths, and multi-course kaiseki meals. Guests typically wear yukata (cotton robes) provided by the inn. A ryokan stay is one of the most authentic cultural experiences Japan has to offer.

What should I wear at the ryokan?

Upon arrival, you'll be provided with a yukata (light cotton robe) and a pair of slippers. You can wear the yukata throughout the ryokan — to dinner, to the onsen, and even for a stroll in the neighborhood. Indoor slippers should be removed before stepping on tatami mats.

Is English spoken at THE KEY HIGHLAND NASU?

Yes, THE KEY HIGHLAND NASU has English-speaking staff who can assist with check-in, dining reservations, and local recommendations. Communication should not be an issue for international guests.

Is there an onsen (hot spring bath)?

Yes, THE KEY HIGHLAND NASU features an onsen for guests. Japanese bathing etiquette requires washing thoroughly before entering the bath. Most onsen have separate bathing times or areas for men and women. Bring a small towel but leave large towels outside the bath area.

Is the onsen tattoo-friendly?

THE KEY HIGHLAND NASU offers private onsen baths, which are ideal for guests with tattoos. Private baths can be reserved for personal use, so tattoo restrictions typically don't apply.

Can I book a private onsen?

Yes, THE KEY HIGHLAND NASU offers private onsen (kashikiri-buro) that can be reserved for personal or family use. This is perfect for couples, families, or guests who prefer privacy. Ask at the front desk upon arrival to reserve a time slot.

Can I store luggage before check-in?

Yes, most ryokans including THE KEY HIGHLAND NASU offer luggage storage for guests arriving before check-in time. You can also use coin lockers at the nearest station or luggage delivery services (takkyubin) to send bags directly from the airport or previous hotel.

Yes, THE KEY HIGHLAND NASU provides complimentary WiFi throughout the property. Connection is available in guest rooms and common areas.

Do you accept credit cards?

Yes, THE KEY HIGHLAND NASU accepts major credit cards including Visa, Mastercard, and JCB. Some ryokans may also accept American Express. It's always good to have some cash as a backup for small purchases.

How do I get to THE KEY HIGHLAND NASU from the nearest station?

About

THE KEY HIGHLAND NASU is an all-inclusive forest resort where the room rate covers gourmet dining, unlimited drinks and ice cream, an indoor Aqua Garden pool and karaoke. Its 36 rooms span six types, from loft rooms to suites with private open-air baths, all in a design-forward, activity-resort style set in the Nasu Kogen woods. A large stone-built bathhouse anchors the onsen side of the stay. It suits travellers who want a self-contained highland escape rather than a traditional inn.

Cuisine

Multi-course kaiseki dinner and traditional Japanese breakfast are typically included in the nightly rate at this luxury ryokan. Premium kaiseki tiers, in-room dining (heya-shoku), and private dining rooms (koshitsu) may be available — request these preferences when booking through Trip.com or Booking.com.

Dietary requests (vegetarian, halal, gluten-free, allergies) should be communicated at booking, not on arrival — the kitchen pre-orders ingredients several days ahead.
