When we heard there was a property people call “Disneyland for dogs”, we honestly took it with a pinch of salt at first. Dog-friendly accommodation has become more common, but most of it amounts to “dogs may also stay” — properties where the dog is genuinely the main character are still rare.
On top of that, our household travels with a dog and a baby at the same time. A facility that is perfect for a dog is not necessarily comfortable for an infant. There was no way to work out that balance just by looking at photos on the official website.
So we went and stayed at Koyaru no Sato Doggy’s Island in Yachimata City, Chiba Prefecture. The conclusion: as a trip with a dog, thoroughly satisfying; as a family trip that also includes a baby, it will not suit everyone. The husband scored it 3 out of 5, the wife 4 out of 5. That one-point gap after the same stay says a lot about the character of this place.
In this article we write up not only the good parts but also, honestly, the inconvenient things we wish we had known before going. If you are planning to come by train, or coming for the hot spring, this is worth reading first.

What this article covers
- Why Doggy’s Island gets called “Disneyland for dogs” (what the breed-segregated dog runs are actually like)
- The reality of getting there by train — the gap between the official guidance and how it felt
- The catch that the hot spring is not “in the hotel” but a separate facility next door with a separate charge
- An honest verdict on the food, and how to calibrate your expectations

- How to judge whether this place suits you or not
What Doggy’s Island is: the basics first
Koyaru no Sato Doggy’s Island is a dog-friendly resort in Yachimata City, Chiba Prefecture. The official website leads with the fact that it has one of the largest natural-grass dog runs in Japan, and the accommodation is split across several types: the main building, villas, glamping and Doggy’s South, among others.
| Item | Details (guide, as of our visit) |
|---|---|
| Property name | Koyaru no Sato Doggy’s Island |
| Address | 624 Koyaru, Yachimata City, Chiba Prefecture |
| Dog runs | Natural grass. Divided into small-dogs-only / medium-to-large-dogs-only / all breeds |
| Accommodation | Main building, villas, Waterfall, glamping villas, Doggy’s South and others |
| Food on site | Several outlets including a restaurant, a café and a Japanese sweets shop |
| Bathing | Use of the adjacent “Koyaru Onsen Mori no Yu” (separate facility, separate charge) |
| By train | Taxi from JR Yachimata Station (official guidance says approx. 15 min) |
Within this table, the two things that most affect how satisfying the trip is are access from the station and bathing. We cover both in detail below.
Getting there from the nearest station
* Official guidance says about 15 minutes; our experience was 20-30 minutes by taxi.
Open in Google MapsWhat was good: “Disneyland for dogs” was not an exaggeration
Starting with the good. This part really is excellent, and almost all of our high rating as dog owners is explained by this section.
1. There are simply a lot of dog runs
The first surprise was the number of dog runs. With a “property with a dog run” you tend to assume one is enough, but here there are several scattered around the grounds, and you can keep moving into a different one as an extension of your walk.
For a dog, a change of environment is clearly more fun than doing laps of the same patch. Even on a one-night stay you end up in a situation where there are still runs you have not been in yet. We came away understanding why people call it “Disneyland for dogs”.
Our dog is very shy around other dogs, but because the runs sit on such a large site, they were able to tear around happily without being chased by anyone else.
2. The separation by breed and size is reassuring
Personally this is the thing we most want to praise. As the official website explains, the dog runs are divided into small dogs only / medium-to-large dogs only / all breeds.
When you have a small dog, letting them into a space where large dogs are running flat out is, frankly, quite frightening. Accidents can happen from the size difference alone, with no ill intent involved. Equally, owners on the large-dog side must find it draining to have to run their dog while watching out for small ones.
Solving both with the simple method of separate dedicated areas is good design. The whole place is built with consideration for dogs — that was our feeling throughout the stay.
3. The whole facility is built on the assumption of dogs
A common pattern at dog-friendly properties is constraints: “dogs are allowed, but only in this wing”, “carry them from here on”. None of that is bad in itself, but it means part of your mind is always on alert.
Doggy’s Island exists because of dogs in the first place, so that low-level fatigue is largely absent. Walking around with a dog is the standard here, not something being accommodated. Not having to apologise as an owner was more comfortable than we had expected.
4. The grass is real
The dog runs being natural grass is also a significant point for a dog’s legs. Compared with concrete or artificial turf, the impact when running and the surface temperature in summer are different. According to the official website there is also dry mist in summer and roofed areas for rain, so the design seems built not to be at the mercy of the weather.
Honestly, what was underwhelming: go without knowing this and you will regret it
This may be the real point of the article. The good parts you can see on the official website; the inconvenient parts only reveal themselves once you stay.
1. It is far from the station. Coming by train eats a lot of time
We think this is the biggest weakness. The official website says roughly 15 minutes by taxi from JR Yachimata Station, but when we actually went, the taxi from the nearest station took 20–30 minutes. We assume it varies with the route, the time of day and the situation at the taxi rank, but either way it is not “just by the station”.
Add a dog and a baby and you have a lot of luggage plus a journey where you are on edge the whole way. Honestly, this place assumes you are arriving by car. Whether or not you have one completely changes how tiring the whole trip is.
- If you can drive: the drawback essentially disappears. It is not far from the expressway interchange either
- If you are coming by train: build the taxi fare and the journey time into your budget from the start
- It is reassuring to ask about arranging the return taxi early, while you are on site
* As an aside, taxi drivers in this area seem to go to Doggy’s Island often — ours took us there with a smile and no hint of reluctance about the dog.
2. The hot spring is not in the hotel; it is a separate facility next door with a separate charge
This was the husband’s biggest complaint. There is a hot spring on the site called “Koyaru Onsen Mori no Yu”, but it is not the hotel’s communal bath — it is an independent day-use hot spring facility next door.
In other words, even as a hotel guest, the procedure is to go outside, travel to that facility, and pay separately to get in. There was a discount for hotel guests (a few hundred yen), but if you are expecting the ryokan-style feeling of wandering down to the communal bath in your room robe, you will definitely be caught out.
This is not to say the hot spring itself is bad. It is that the logistics are a hassle. Simply not being able to go straight back to your room after your bath raises the psychological barrier more than you would think. The husband’s honest view was that he wished they would just put a hot spring inside the facility. (And since it was about a ten-minute walk, he got cold again on the way back.)
- Bathing means using the adjacent separate facility “Koyaru Onsen Mori no Yu”
- There is a guest discount, but the bathing fee is still payable separately
- Because it operates as a day-use hot spring, you cannot bathe late at night or early in the morning
- Rates and opening hours are subject to change, so check the official website in advance
Choose this place because you want to stay at a hot-spring ryokan and your expectations will be misaligned. The right approach is to accept that this is a dog resort, not an onsen inn.
3. The food is not “really delicious”
Writing this honestly too. There are several food outlets on site, so the choice itself is plentiful. But this was not a property where the cooking moves you.
It is not bad. It is perfectly edible. But whether it matches the level you would expect from the room rate — honestly, that falls a little short. For people whose values put food as the main event of a trip, it probably will not land.
Then again, this too reflects the character of the place. This facility genuinely exists for dogs, and the resources are directed to the dog side. Understood that way, it makes sense.
* On that note, there was even a buffet for the dogs. (Ours is so shy around other dogs that they would not eat a single bite of it, though.)
4. From a parent’s angle: the floor of the room bothered us
This was an unexpected blind spot specific to a dog-oriented facility. Regarding the room we stayed in, the wife felt “I would rather not let a baby crawl on this.”
Because the room is designed on the assumption that dogs will be on the floor, the standard applied to floor condition differs from that of a parent with an infant. This is not a claim that the facility is unclean; it is that the user they have in mind is different. A floor that is comfortable for a dog and a floor that feels safe for a baby at the crawling stage are not necessarily the same thing.
The realistic countermeasure is to bring something you can lay on the floor — a play mat, bath towels, a picnic sheet. Having one or not makes a considerable difference to how easy the room is to spend time in.
We have written a detailed article on what to pack for travelling with a dog, so please have a look at that as well.

Who we would and would not recommend this to
Recommended for
- People who can drive there: the biggest weakness, access, disappears, so the rating goes up a notch
- People who want to let their dog really run: the number and size of the dog runs can be the whole point of the trip
- People with either a small or a large dog who worry about the size gap: the breed-based separation is a big reassurance
- People with several dogs: you can switch between the all-breed and dedicated areas
- People whose aim is “playing outside” rather than “spending time in the room”: that matches the design philosophy of the place
Harder to recommend for
- People expecting a hot-spring ryokan: bathing is a separate facility next door with a separate charge, and the logistics will likely feel like a hassle
- People who put food at the centre of a trip: not bad, but not at a level that impresses
- People who can only travel by train: the taxi ride from the station is more of a burden than you expect
- People with a baby at the crawling stage: bringing floor coverings becomes a prerequisite
Put another way, the dividing line is whether you can accept this as “a trip for the dog”. For people who can, it is a very good facility; ask for grown-up luxuries at the same time and the score drops.
Practical tips worth knowing before you go
1. Drive there if you can
To repeat, this is the one that matters most. With a dog and a baby and a lot of luggage, 20–30 minutes in a taxi from the station quietly wears you down. With a car you also have far more freedom once you arrive.
2. If you come by train, budget the taxi fare and time from the outset
Do not assume it will sort itself out once you reach the station. Estimating the round-trip taxi fare and journey time in advance makes a real difference to how relaxed you are on the day. It is also reassuring to discuss the return pickup with the front desk at check-in.
3. If you are going to the hot spring, fix a time and stick to it
Because it requires travelling to the neighbouring facility, “whenever we happen to have a free moment” means you will miss it. The trick is to decide on a specific time after check-in. It has opening hours, so a late-evening whim may not make it.
4. With a baby, bring something to lay on the floor
A play mat, large bath towels, a picnic sheet. They are bulky, but having one completely changes how at ease you feel in the room. We recommend preparing one for the child separately from the dog’s mat.
5. Check in advance which documents, such as vaccination certificates, are required
Dog-friendly facilities ask you to present certificates for rabies and combination vaccinations. Do not forget to bring them on the day.
Our rating (out of 5)
At Kozure Tabi we score every property we have actually stayed at on the same five criteria, each out of 5. To keep the standard consistent from one property to the next, we always use the same five: travelling with kids, travelling with dogs, bath and sauna, food, and value. The overall score is the average of the applicable criteria. Criteria that do not apply are marked "Not applicable" and excluded from the overall score.

Frequently asked questions
Q. So is the “Disneyland for dogs” thing true?
A. In terms of the number of dog runs and the separation by breed, we felt the description is not an exaggeration. But if you picture “an all-round resort for the adults too”, it is slightly off. The dog is the star, and that is that.
Q. Can you get there by train alone?
A. You can, but a taxi from the nearest station is essential. Official guidance says about 15 minutes; our experience was 20–30. Leave yourself room in both time and budget.
Q. Is there a communal bath in the hotel?
A. As far as we could confirm, bathing means using the adjacent “Koyaru Onsen Mori no Yu”. It is a separate facility with a separate charge, and there appears to be a discount for hotel guests. Please check the official website for the current arrangement.
Q. Is it all right with a baby?
A. Staying itself was possible, but because the facility is built around dogs, if you have a child at the crawling stage we strongly recommend bringing something to lay on the floor.
Q. Should I have high hopes for the food?
A. There is plenty of choice, but this was not a property whose flavours impress. Go in with modest expectations and it should sit about right.
Q. Can a small dog play here safely?
A. There is a dog run exclusively for small dogs, so anxiety about the size difference is greatly reduced. This is the single biggest reason we rate this facility.
Summary: if you can accept it as “a trip for the dog”, it is a good place
- Good: many dog runs, divided into small / medium-to-large / all breeds. Natural grass. Designed around dogs, so far less low-level stress
- Bad: far from the station — 20–30 minutes by taxi if you come by train. The hot spring is a separate facility next door with a separate charge. The food does not match the price bracket
- From a parent’s angle: the rooms are set up for dogs, so a baby at the crawling stage needs floor coverings
- Scores: husband 3 / wife 4 (out of 5). With the dog alone, the wife gives it 5
- Verdict: strongly recommended for people who can drive there and can make the dog the star
Opinions on this property divide not because it is poorly executed, but because it is so unmistakably clear who it is for. The investment in dogs is thorough, and in exchange the luxuries adults tend to want — the hot spring, the food — are relatively thin. Whether you accept that allocation decides your satisfaction outright.
We went under what is arguably the greediest set of conditions: with a dog and a baby. The result was husband 3, wife 4. Had we taken only the dog and driven there, we suspect both of us would have scored it close to 5.
You want your dog to run flat out. You want them to play without worrying about the size difference with other dogs. If that is your clear aim, this is a facility worth going to. If instead you want “a trip where every member of the family gets their own enjoyment”, we would suggest sorting out where you place your expectations before you book.
* As an aside, our dog had been a little depressed since the baby arrived, not getting as much attention as before, and the symptoms improved after visiting this place — so in that sense it was an extremely good facility.
