Keikyu EX Inn Tokyo Nihonbashi opened in 2020, and that freshness is still very much felt the moment you walk in. Calm materials, an efficient layout, and a two-minute walk to Kayabacho Station make it one of the better value choices on the east side of Tokyo Station. For solo travelers or anyone who wants genuine proximity to the city’s rail network without paying Marunouchi prices, this property is genuinely hard to beat.
Overview
The hotel’s 10-floor building houses 142 rooms, 114 of which are singles — a clear signal that the property is designed for the solo business traveler and the independent sightseer. Room types include a standard semi-double, an EX double with a 160 cm bed, a barrier-free semi-double, and a women’s floor on the 8th level. The interior still has that just-opened quality: clean finishes, uncluttered sight lines, and a layout that never wastes space.
Finding the entrance is part of the experience. At street level, the hotel shares its facade with a PRONTO café; the actual hotel entrance sits beside the café, and the front desk is up on the second floor, reached via a staircase with a slightly hidden, labyrinthine feel. Check-in is available at a staffed counter or at a self-service machine, which is a real convenience when you’re arriving late and just want to get to your room.
Room & Amenities
My semi-double on the 9th floor measured around 13 square meters — compact, but thoughtfully planned. The entrance corridor is wide enough to pass through with a large rolling suitcase without having to tilt or negotiate, and the closet area beside the entrance is deep enough to store that same case standing up underneath the hanging rail. It’s exactly the kind of quiet, considered detail that makes a stay more comfortable without ever announcing itself.
Every room in the hotel features a bed developed in collaboration with Simmons. That comes through in the quality of sleep — the mattress genuinely supports rather than just existing. Two pillow firmness options let you personalise a little. Two-piece pajamas (top and bottom separate) are provided in place of the one-piece gown common at this tier, which matters more than it sounds on a cold night. A bedside panel controls all room lighting from one point, and USB ports alongside a standard outlet sit within arm’s reach of the pillow.
An air purifier with a built-in humidifier is included — a considered touch given how dry central Tokyo gets from November through March. The mini-fridge keeps drinks cold. Note that bottled water isn’t stocked in-room, but a welcome coffee is available in the lobby and vending machines on the 2nd floor cover hydration from there. Blackout and lace curtains together give full light control. Disposable slippers, a deodorizing spray, and a full-length mirror round out the basics.
The unit bathroom comes with a washlet toilet and a SALONIA Speedy Ion Dryer — a name-brand choice that dries hair thoroughly without the overheating that plagues generic hotel dryers. Single and semi-double rooms use this combined unit configuration; double and EX double rooms come with a separate bathroom. The women’s floor additionally provides DHC skincare products alongside standard amenities. In the shared lobby, a self-service amenity corner offers combs, skincare items, and tea bags. Hair irons and international plug adapters are on loan from the front desk. Three washer-dryer units and vending machines stocked with water, soft drinks, and alcohol are on the 2nd floor. The hotel operates an ECO cleaning policy — no daily room service for consecutive-night stays, with towel replacement on request.
Dining & Breakfast
Breakfast is served at PRONTO on the 1st floor between 7:00 and 11:00, with five set options available, including takeout formats for early departures. Each set comes with a drink. The seating mixes relaxed bench spots with counter seats that have power outlets, making it equally suited to a leisurely morning or a quick working breakfast. I went with the Japanese set — grilled salmon, natto, a side dish, rice, and miso soup — which felt pleasingly incongruous on a PRONTO menu but was well-cooked and satisfying in the way a proper traditional breakfast should be.
For dinner, the most memorable option in the immediate area is REWILD OUTDOOR TOKYO, encountered on a walk back through Nihonbashi. What looks like an outdoor goods shop from the street opens into a full indoor camping restaurant: low wooden tables with camping tools, outdoor chairs, greenery hanging from the ceiling, recorded nature sounds, and a central bonfire screen casting warm light across the room. Food arrives partially prepped; you cook at the table using a gas burner and camping cookware — hot sandwiches in a sandwich press, pasta in a mess tin, smoked dishes over a small flame. Survival-knife cutlery reinforces the aesthetic without tipping into theme-park territory. The atmosphere is welcoming to solo diners despite being built for groups, and the menu changes with the season.
Location & Access
The closest station is Kayabacho — two minutes on foot — served by both the Tokyo Metro Tozai and Hibiya lines. That pairing gives direct access to Shinjuku, Ginza, Roppongi, and the Shinkansen connections at Tokyo Station without a transfer. Nihonbashi Station (Ginza, Asakusa, and Hanzomon lines) and Hatchobori are also within comfortable walking distance, giving the hotel an unusually broad rail catchment for its size. If you’re walking to Tokyo Station directly, the Yaesu exit is around 10 to 12 minutes on foot.
The neighborhood itself is worth exploring slowly. Nihonbashi holds one of the densest concentrations of Meiji and Taisho-era commercial architecture in Tokyo, alongside specialist shops for lacquerware, Edo crafts, and traditional foods. The Pokémon Center and Pokémon Café are nearby in the Nihonbashi Takashimaya complex, worth noting for families traveling with younger kids.
The standout evening excursion from the hotel is the rooftop garden on the 6th floor of KITTE, in front of the Marunouchi South Exit of Tokyo Station — about a 15-minute walk. The roughly 1,500 m² open terrace is free to enter and offers a close overhead view of the illuminated Marunouchi Station building: the 1914 red-brick structure designed by Tatsuno Kingo, whose Byzantine-style dome was lost in the war and meticulously restored in 2012 to its original form. Tokyo Station is illuminated from sunset until 9:00 PM, and the glass safety fence means children can look out unobstructed alongside you.
Final Verdict
Keikyu EX Inn Tokyo Nihonbashi gets the fundamentals right: Simmons beds, genuine blackout curtains, a humidifying air purifier, two pillow options, and a well-proportioned room — all within two minutes of Kayabacho Station and easy walking distance of Tokyo Station. The PRONTO breakfast is more flexible and better-cooked than a standard hotel buffet, and REWILD OUTDOOR TOKYO provides an evening experience that’s genuinely hard to find anywhere else in central Tokyo. Rates vary by season — check current prices on Agoda. For travelers who want the Tokyo Station area without the Marunouchi price tag, this is one of the most considered options on the east side of the tracks.
