HOTEL KARUTA 赤坂 (ADULTS ONLY), Tokyo

The hotel sits in a quieter part of central Tokyo compared to areas like Kabukicho, yet remains well-connected by subway. Akasaka Station is a 3-minute walk, providing easy access across the city and to Haneda Airport (15 km). Nearby landmarks include the Hundertwasser Millennium Clock (600 m) and Akasaka Biz Tower Shops & Dining (2-minute walk). Several restaurants and cafés are within 0.3-0.5 km, offering a range of dining choices. The neighbourhood is pleasant and clean, ideal for exploring on foot.

All rooms are adults-only and feature private bathrooms with a bath, shower, bidet, hairdryer, and slippers. Suites offer a separate living room and bedroom, with 1-2 beds. Some rooms come with a private open-air bath on the balcony (rooms 501-503). Select rooms also include a karaoke machine, private bar, fireplace, or two private pools. Rooms are spacious and spotlessly clean, equipped with king-size beds, large sofas, huge TVs, and free WiFi. Free amenities include champagne, yukata, cosplay costumes, and toiletries. The architecture blends Japanese and Western styles, and the rooms match photos exactly.

The hotel does not have a restaurant, bar, or breakfast service. However, wine and champagne are available at an extra cost. A free welcome drink is included with the stay. For meals, several dining options are within a short walk, including Japanese, Korean, and Italian restaurants within 0.3-0.5 km from the hotel. This makes it easy to find food without traveling far, though the property itself focuses on in-room amenities rather than dining facilities.

The highlight is the private open-air bath available in rooms 501, 502, and 503, offering a secluded outdoor bathing experience on the balcony. Several rooms also include a karaoke machine, private bar, fireplace, and even two private pools among other playful amenities. Free cosplay costumes, yukata, and champagne are provided in the room. These amenities are designed for couples or adults seeking a fun, private leisure experience. There is no communal gym or spa; the leisure facilities are all in-room.

The hotel offers free WiFi in all rooms, a 24-hour front desk for late arrivals, and 24-hour security with CCTV, key card access, and smoke alarms. A lift serves all floors. No parking is available, so use public transport; Akasaka Station is a 3-minute walk. Pets are not allowed. An invoice can be provided for business travellers. Early check-in is possible for a fee, but consecutive-night stays require separate bookings. Payment can be made by American Express, Visa, Diners Club, JCB, NICOS, or UC.
