Tennomaru

天の丸

Does Tennomaru allow tattoos? Yes!

Nothing to cover

Tennomaru stands on a 380-meter hilltop above Gamagori, and its bath page says in one line that tattooed guests may bathe. The spring water is in the open-air tubs on the 4th floor, which look over the town lights and Mikawa Bay.

The inn's bath page lists tattoos as allowed in the baths, with no cover asked for and no hours attached. That line sits under the list of every bath in the building: the two view open-air baths, the two large baths and the two private open-air baths. The baths are for staying guests only at present.

The bath

The spring here is Gamagori's Bihakusen, an alkaline simple spring that comes out of the ground at 28.9°C. The inn calls it a beauty bath, clear and soft on the skin, and lists it for neuralgia, muscle and joint pain, frozen shoulder, bruises and sprains, chronic digestive trouble, cold sensitivity and recovery from fatigue. It runs only to the open-air tubs.

Two view open-air baths sit on the 4th floor. Southern Cross faces Mikawa Bay, and Swan Cross looks over the water by day and the town lights after dark. Both are open 3 to 11 p.m. and 6 to 9 a.m. The two large baths, Mikawa-no-yu and Aoi-no-yu, are in the basement behind big windows on the bay and keep the same hours; the inn states that their water is not hot spring water.

Two private open-air baths on the 4th floor, Sapphire and Topaz, take the spring. Each is booked for 45 minutes at ¥3,300, from 3 to 10 p.m., and neither is open to day visitors. The Geshokyu rooms have an open-air tub on a 7.2-square-meter terrace, and the inn says that tub is not hot spring water.

The hotel

Tennomaru belongs to Kaiei Ryokans, a group that markets its inns for anniversaries. Every room has a wide view over the woods to Gamagori and the bay. Room types run from the Geshokyu Japanese-Western rooms with a low bed and a terrace tub, through the plain Japanese Nanseikyu rooms and corner suites, to single rooms on the mountain side with no view. Dinner is in the restaurant Hoshi-no-fune, which looks over the night view. Older car navigation units may still show the building's former name, Mikawa Heights.

Good to know

Getting there

From Tokyo, the inn suggests the Hikari Shinkansen to Toyohashi, about 1 hour 20 minutes, then 15 minutes on the Tokaido Line to Gamagori. Parking for 100 cars is free.

How we know

Confirmed from official site (the facility list at the foot of the inn's bath page)

タトゥー・入れ墨の入浴可

The operator’s own wording. Show it if anyone asks.

Best for: bathing with tattoos uncovered in an open-air tub that looks down on Gamagori and Mikawa Bay at night

Only the open-air baths carry hot spring water: the view open-air baths Southern Cross and Swan Cross on the 4th floor and the two private open-air baths. The inn says its large baths, Mikawa-no-yu and Aoi-no-yu in the basement, are not hot spring water, and that the open-air tubs in the Geshokyu rooms are not hot spring water either. Private open-air baths: 45 minutes for 3,300 yen, by reservation, 3 to 10 p.m. Day-use bathing is suspended for now.
