OMO5 Tokyo Gotanda by Hoshino Resorts — the 14th-floor dog garden no other Tokyo hotel can match
Did you know there's a hotel in Tokyo with a 160 sqm off-leash dog garden on the 14th floor — where guests who bring their dogs say the trip is better for it than coming alone? OMO5 Tokyo Gotanda by Hoshino Resorts is exactly that place: an urban hotel from the Hoshino Resorts group that actually invested in a proper rooftop green space for dogs to run freely, not just a "pet-friendly" sticker in the lobby. Add a 1-minute walk to JR Gotanda on the Yamanote Line — the loop line connecting every major neighbourhood in the city — and you have a hard-to-beat base for a Tokyo trip with your dog.
OMO5 Tokyo Gotanda sits at 1-5-2 Higashi-gotanda in Shinagawa-ku — a 1-minute walk from JR Gotanda West Exit, and that is the first thing guests who travel with dogs notice. Gotanda is on the Yamanote Line, the loop railway that circles Tokyo and connects every major district in the city. Shibuya, Shinjuku, Harajuku, Tokyo Station — you can reach all of them from the same platform without a transfer. Arrive with your dog, walk straight to the hotel in under a minute, and skip the exhausting journey that comes with staying further from a main line.
"My dog was running around the 14th-floor dog garden all morning and completely knocked out by afternoon — so much better than hunting for a dog park in the city."
What sets OMO5 Gotanda apart from every other pet-friendly hotel in Tokyo is unmistakably the 160 sqm dog garden on the 14th floor, open for off-leash play. This isn't a small patch of grass near the lobby — it's a generous indoor green space high above the city, with views of the Shinagawa skyline. Wake up in the morning, take the lift up with your dog, and let them run free without having to trek across town to find a dog park. Many guests say this single feature is the reason they chose OMO5 over any other option.
The Dog Friendly Twin room at 22 sqm is designed with dog owners in mind from the ground up. The floor uses non-slip tatami so dogs can run without sliding, the sofa is upholstered in water-repellent fabric, and a dog bed is included in the room as standard. These are the details Hoshino Resorts thought through carefully — the difference between a hotel that merely tolerates pets and one that actually designed for them. If you need more space, a Dog Friendly Deluxe at 30 sqm is available, which suits medium-sized dogs more comfortably.
The pet fee is ¥5,093/dog/night, which is the Hoshino Resorts chain-wide standard, and the hotel does not impose a size or weight limit on dogs — unlike many Tokyo hotels that cap at 8–10 kg. The requirements are that dogs must meet a basic behaviour standard (no biting, no excessive barking, no jumping up, toilet trained) and be up to date on vaccinations. If your dog already meets that standard, everything else is straightforward.
The broader feel of the property reflects the OMO brand's urban-casual identity, which leans into local neighbourhood discovery rather than formal luxury. The rooms sit at a compact size typical of Tokyo mid-range, and the vibe is energetic rather than refined. For travellers who prioritise location, dog facilities, and a genuine Hoshino Resorts-level hospitality standard — without paying for five-star surroundings — OMO5 Gotanda lands exactly where it needs to.
Before you book, it's worth knowing that OMO5 Gotanda opened in late 2024, so the review count online is still building up — the 8.6 score comes from an early review base that will likely grow. Dog Friendly rooms are limited in number, so the hotel needs to be informed at the time of booking that you are bringing a dog. Leave it until check-in and there may not be a suitable room available.
In short, OMO5 Tokyo Gotanda is the clearest answer in Tokyo for anyone who wants to travel with a dog of any size without compromising on location. A 160 sqm off-leash garden on the 14th floor simply does not exist anywhere else in the city, and a 1-minute walk to JR Gotanda Yamanote Line leaves almost nothing to complain about in terms of access. Starting from ¥18,500/night for the Twin room plus ¥5,093 for your dog.
