Overview

At Tsukubasan Hotel Aokiya, you stay on the slopes of Mt. Tsukuba with the vast Kanto Plain spreading out below you. From the lobby, selected rooms, and rooftop open-air baths, you can watch the countryside change from green fields and distant mountains to glowing city lights after dark.

On a clear day, the view can reach as far as Mt. Fuji and the Southern Alps. Sunset brings one of the most memorable scenes, as the distant peaks catch the evening light before the cities below begin to sparkle.

Mt. Tsukuba has appeared in Japanese poetry since the time of the Manyoshu and remains one of Ibaraki’s best-known natural landmarks. You can combine mountain walks, shrine visits, cable car journeys, and seasonal sightseeing with Japanese kaiseki cuisine and long soaks overlooking the plain.

Accommodation

You can choose from Japanese rooms, Japanese-Western rooms, special rooms on the Tokimachi Floor, and rooms with private open-air baths. Current room plans are non-smoking, and the view depends on the category you select.

The Tokimachi Floor contains special Japanese and Japanese-Western rooms designed around the changing sky, landscape, and light. Every room on this floor includes a private open-air bath and looks across the Kanto Plain. During the day, you can see the fields and distant mountains. At night, the lights of Tsukuba and the wider plain create a completely different atmosphere.

The special Japanese-Western room is limited to one room. It combines a Japanese sitting area with Western beds and a private open-air bath. The layout gives you the character of a traditional stay while allowing you to sleep in a bed.

The special Japanese room keeps a full tatami layout with futon bedding and a private open-air bath. Wide views place the Kanto Plain directly in front of you, with Mt. Fuji visible in the distance when the air is clear.

The standard Open-Air Bath Room gives you a private outdoor tub facing the towns, fields, and distant skyline below Mt. Tsukuba. Baths come in ceramic and hinoki cypress designs. You cannot select the tub style in advance, but both give you a private place to bathe while enjoying the view.

The standard Japanese room has a 10-tatami layout with futon bedding. Depending on the category you reserve, your room faces either Mt. Tsukuba or the Kanto Plain and city lights. A mountain-facing room brings you closer to the wooded slopes, while a night-view room lets you watch the landscape brighten after sunset.

A Japanese-Western night-view room is also available. You can relax on tatami during the day and sleep in Western beds at night while looking across the illuminated plain.

Your room includes a television, refrigerator, safe, tea set, yukata, towels, toiletries, hairdryer, air conditioning, and a toilet with bidet functions. Equipment may differ slightly between room categories.

Dining

Dinner brings you colourful Japanese kaiseki cuisine prepared with seasonal ingredients and local flavours. The menu changes according to the time of year and the ingredients available that day, allowing you to experience a different side of Ibaraki with each visit.

Selected dinner plans feature Miraiton, a branded pork raised by approved producers in Ibaraki. Its tender texture and gently sweet fat work particularly well in a hot ceramic-plate steak. This dish appears alongside seasonal appetisers, sashimi, simmered dishes, rice, soup, and other parts of the kaiseki course.

Your dining location depends on the room and plan you reserve. You may enjoy dinner in a private dining room or at the Japanese dining venue. In the dining area, the show kitchen allows freshly prepared tempura and other hot dishes to reach your table soon after cooking.

Selected room categories include a private dinner setting. Other plans use the Japanese dining room, while daily arrangements may occasionally change the assigned venue. Breakfast is normally served in a shared dining or banquet hall.

Onsen and Wellness

Natural Tsukuba Onsen water fills the rooftop open-air baths and the large indoor bathing areas. The spring is classified as an alkaline simple spring and has a smooth feel against the skin. Traditional bathing indications include fatigue and neuralgia, while the water is also associated with softer-feeling skin after bathing.

Unjo-no-Yu is the signature panoramic open-air bath. Positioned at an elevation of around 300 metres, the bath gives you a 180-degree outlook across the Kanto Plain. With no roof above the main bathing area, you can soak beneath open skies and watch the view change throughout the day.

In the afternoon, fields and towns stretch toward the horizon. Around sunset, Mt. Fuji may appear against the evening light when visibility is good. After dark, the city lights below resemble scattered jewels, while clear nights bring wide views of the stars.

Ginga-no-Yu is the large indoor observation bath. Wide windows keep the landscape in view while protecting you from cold, wind, or rain. Washing stations are provided, allowing you to shower before settling into the warm water.

The shared baths are open from 15:00 until midnight and again from 05:30 until 08:30. Separate facilities are provided for men and women. The men’s bathing area also includes a sauna, available from 17:00 to 20:30.

The spring water is not presented as a continuously source-flowing system, so you should not describe the public baths as kakenagashi. The main appeal lies in the alkaline water and the exceptional view from both the indoor and outdoor bathing areas.

Guests with Tattoos

You cannot use Unjo-no-Yu, Ginga-no-Yu, or the other shared bathing facilities if you have tattoos. Choose a room with a private open-air bath when you need a private bathing space.

Facilities

Inside Aokiya, you can relax in the panoramic lobby lounge while looking across the Kanto Plain through large windows. In the evening, the lounge takes on the atmosphere of a bar, giving you a comfortable place to enjoy a drink while watching the city lights.

The property also includes a Japanese dining venue with a show kitchen, private dining rooms, large and small banquet halls, a convention hall, a shop, drink vending machines, and a designated smoking room. The banquet and conference spaces can support group meals, celebrations, meetings, and organised events.

For evening entertainment, Karaoke Lounge Starlight has space for larger gatherings, while the Kirara karaoke rooms provide a more private setting. Wireless internet access is available in the lobby and selected shared areas.

The shop carries local confectionery, Mt. Tsukuba souvenirs, regional food, towels, and crafts. Complimentary parking is available on a first-come basis.

Activities

Mt. Tsukuba gives you several ways to enjoy the landscape. You can hike toward its two peaks or use the cable car and ropeway to reach higher viewpoints with less walking. Clear weather brings broad views across Ibaraki and the Kanto region.

Tsukubasan Shrine stands close to the property and has long been associated with the mountain’s spiritual history. You can walk through its grounds, see the traditional buildings, and begin mountain routes from the surrounding area.

Ibaraki Flower Park makes an easy seasonal excursion, with flowers, gardens, and outdoor displays changing throughout the year. You can also explore the wider Tsukuba Science City area or plan trips toward Kasama, Lake Kasumigaura, Ushiku Daibutsu, and the pottery town of Mashiko.

You can experience Aokiya’s baths without an overnight stay through the daytime bathing service. Day access is normally available between 12:00 and 15:00, subject to operating conditions.

Additional Features

Standard check-in begins at 15:00, and check-out is at 10:00. Arrival times depend on your dining plan, with earlier arrival required when dinner is included.

You can reach the Mt. Tsukuba area by direct shuttle bus from Tsukuba Station, with the journey taking around 40 minutes. By car, the drive from the Tsuchiura-Kita interchange normally takes around 30 minutes.

Wheelchairs are available to borrow, and a slope supports access at the entrance. Complimentary parking, banquet facilities, day bathing, private dining plans, and rooms with private open-air baths allow you to shape your stay around sightseeing, celebrations, or quiet time on the mountain.
