Nine Hours Shinjuku Review: What It’s Like Staying in a Japanese Capsule Hotel

When many travelers imagine staying in Japan, they often picture traditional ryokan, modern hotels, or luxury accommodations with views of Mt. Fuji. However, one of the most unique experiences you can have in Japan is spending a night in a capsule hotel.

During a recent trip to Tokyo, I stayed at Nine Hours Shinjuku-North, a modern capsule hotel located near Shin-Okubo Station. It was my first time staying in a capsule hotel, and I was curious to see whether it was simply a budget accommodation or a genuinely interesting part of Japanese travel culture.

What surprised me most was the number of international travelers staying there. During my visit, the vast majority of guests appeared to be visitors from outside Japan, making it feel almost like a global travel hub in the middle of Tokyo.

In this review, I’ll share my honest experience staying at Nine Hours Shinjuku, explain what the capsule rooms are actually like, and help you decide whether a Japanese capsule hotel is worth trying during your trip.

What Is Nine Hours Shinjuku?

A Modern Japanese Capsule Hotel

Nine Hours is one of the most well-known capsule hotel brands in Japan, with locations in major cities such as Tokyo, Osaka, Nagoya, Sendai, and Fukuoka.

Unlike traditional capsule hotels that often feel old-fashioned, Nine Hours focuses on a clean and minimalist design. Everything from the sleeping pods to the shared facilities follows a simple concept, creating an atmosphere that feels modern and efficient.

The name “Nine Hours” comes from the idea that travelers only need three basic things during a short stay: one hour to shower, seven hours to sleep, and one hour to get ready before leaving.

Another unique feature is the optional sleep analysis service, which allows guests to receive insights about their sleep patterns after their stay. This technology-focused approach helps distinguish Nine Hours from many other capsule hotels in Japan.

Location and Access from Shinjuku Station

Nine Hours Shinjuku-North is located in the Shin-Okubo area, one of Tokyo’s most multicultural neighborhoods.

Although the hotel is often associated with Shinjuku, it is actually closer to Shin-Okubo Station, which can be reached in just a few minutes on foot. The area is known for its restaurants, cafés, and international atmosphere, making it a convenient place to stay while exploring Tokyo.

Shinjuku Station is also within walking distance, giving guests easy access to one of Tokyo’s largest transportation hubs.

For travelers arriving late at night or leaving early in the morning, the location is particularly convenient.

Why I Chose to Stay Here

I chose Nine Hours Shinjuku primarily because I needed a simple place to stay while spending a few days in Tokyo.

Hotel prices in Tokyo can be surprisingly expensive, especially on weekends, and I wanted to experience something uniquely Japanese rather than booking a standard business hotel.

Since I had never stayed in a capsule hotel before, Nine Hours seemed like the perfect opportunity to see what the experience was really like.

I was also curious about the sleep analysis system and wanted to understand why so many international travelers choose capsule hotels during their trips to Japan.

My First Impressions After Checking In

The Minimalist Design and Atmosphere

The first thing I noticed after arriving at Nine Hours Shinjuku-North was how simple and modern everything looked.

Unlike many hotels that use decorative interiors or traditional Japanese designs, Nine Hours follows a minimalist concept. The lobby, hallways, lockers, and sleeping areas all feature clean lines, bright lighting, and a simple black-and-white color scheme.

At first, the design almost felt futuristic. Everything seemed intentionally designed to focus only on the essentials, creating a calm and organized atmosphere.

Even though many guests were checking in and out, the hotel never felt chaotic. The simplicity of the design helped the entire space feel clean, quiet, and easy to navigate.

How the Check-In Process Worked

The check-in process was surprisingly straightforward.

After arriving, I completed the check-in procedure and received access to my locker and sleeping area. The staff were friendly, and the process was simple even for international travelers who may not speak Japanese.

One thing I appreciated was how organized everything felt. Guests are provided with clear instructions, and the flow from check-in to the locker area and capsule floor is easy to understand.

The overall experience felt efficient without feeling rushed, which matches the concept of the Nine Hours brand.

Who Was Staying There?

One of the most interesting things I noticed during my stay was the type of travelers staying at the hotel.

To be honest, it felt like almost everyone was visiting from overseas. Throughout my stay, I heard many different languages being spoken, and international travelers clearly made up the majority of guests.

This did not feel like a typical business hotel used mainly by Japanese office workers. Instead, it felt more like a travel hub where people from around the world were sharing the same space while exploring Tokyo.

Because of the international atmosphere, I think many travelers feel comfortable staying here even if it is their first time visiting Japan. The hotel seemed designed with international visitors in mind, and the overall environment felt welcoming and easy to use.

Seeing so many foreign travelers also reminded me how popular capsule hotels have become as a uniquely Japanese travel experience. For many guests, staying in a capsule hotel is not just a place to sleep — it is part of the trip itself.

What the Capsule Room Was Like

Inside the Sleeping Pod

The capsule itself was much larger than I expected.

Before my stay, I imagined the sleeping pod would feel cramped or uncomfortable, but once I climbed inside, there was enough space to lie down comfortably and relax. While you obviously cannot stand up inside the capsule, it did not feel as restrictive as I had imagined.

The interior was simple and clean, with soft lighting and enough room for essentials such as a phone, wallet, or water bottle. The design focused entirely on creating a comfortable sleeping environment without unnecessary distractions.

One thing I liked was how futuristic the pod felt. It almost felt like sleeping inside a small private space station rather than a traditional hotel room.

Comfort, Privacy, and Noise Levels

One of the biggest concerns many travelers have about capsule hotels is privacy.

While capsule hotels are still shared accommodations, I felt that Nine Hours did a good job of creating personal space for each guest. Once the curtain was closed, the sleeping pod felt surprisingly private.

Of course, it is not completely silent. Guests occasionally walk through the sleeping area, and you may hear people entering or leaving their capsules. However, during my stay, most guests were respectful and kept noise to a minimum.

Because the majority of travelers seemed to be using the hotel simply as a place to sleep, the atmosphere remained quiet throughout the night.

Anyone expecting the complete privacy of a traditional hotel room should adjust their expectations, but for a shared accommodation, I thought the experience was more comfortable than expected.

Is It Comfortable for One Night?

For a short stay, I would definitely say yes.

The capsule was clean, comfortable, and provided everything I needed for a good night’s sleep. If your goal is to spend most of the day exploring Tokyo and simply need a convenient place to shower and sleep, a capsule hotel like Nine Hours works very well.

Would I stay there for an entire week? Probably not. Having a private room becomes more appealing during longer trips. However, for one or two nights, I think the experience is not only practical but also part of the fun of traveling in Japan.

For many international visitors, staying in a capsule hotel is something uniquely Japanese that you cannot easily experience in most other countries. Because of that, I think it is worth trying at least once, even if only for a single night.

The Sleep Analysis Experience

What Is the Nine Hours Sleep Analysis?

One of the most unique features offered by Nine Hours is its optional sleep analysis service.

Unlike a typical capsule hotel stay, guests can choose to participate in a program that collects sleep data during the night and provides a report afterward. The goal is to help guests better understand their sleeping habits and overall sleep quality.

This combination of accommodation and technology is one reason why Nine Hours has gained attention from both domestic and international travelers. It transforms a simple overnight stay into something a little more interesting and memorable.

For travelers who enjoy trying new technology or learning more about their health, the sleep analysis feature adds an extra layer to the experience.

How It Worked During My Stay

During my stay, I participated in the sleep analysis program provided by Nine Hours.

The process was simple and did not require much effort from me. After following the instructions provided by the hotel, I slept as usual and later received information about my sleep patterns.

What I liked was that the system did not interfere with the overall hotel experience. The capsule remained comfortable, and I did not feel like I was participating in a complicated experiment. Instead, it felt like a natural part of the stay.

Since many travelers are already interested in improving their sleep, it was interesting to see how a hotel could provide useful data while also offering accommodation.

My Personal Results and Thoughts

After receiving my sleep analysis results, I found the experience more interesting than I expected.

Rather than simply telling me whether I slept well or poorly, the report provided insights into my sleeping habits and overall sleep quality. While I would not say it completely changed the way I think about sleep, it definitely made me more aware of my sleeping patterns.

What impressed me most was that this feature turned an ordinary overnight stay into something memorable. Even if two capsule hotels offer similar rooms and facilities, the sleep analysis service gives Nine Hours a unique identity that helps it stand out.

For travelers who are curious about sleep technology or simply want to try something different during their trip to Japan, I think the experience is worth exploring. Even if you are mainly staying for convenience, receiving personal sleep data afterward adds an unexpected and interesting part to the stay.

Facilities and Amenities

Showers and Bathrooms

One thing I appreciated about Nine Hours Shinjuku-North was how clean the shower and bathroom areas were.

Since capsule hotels rely heavily on shared facilities, cleanliness is extremely important, and the hotel did a good job maintaining the space during my stay. Everything felt modern, organized, and easy to use.

The shower area was simple but functional, providing everything needed after a long day of exploring Tokyo. Even though many guests were staying at the hotel, the facilities never felt overcrowded when I used them.

For travelers who may be worried about sharing bathrooms with other guests, I found the experience much more comfortable and cleaner than expected.

Lockers and Luggage Storage

Because the sleeping pods are designed primarily for sleeping, larger belongings are stored separately in lockers.

Each guest receives access to a locker where they can store clothes, backpacks, and other personal items during their stay. This helps keep the sleeping area quiet and uncluttered.

If you are traveling with a normal backpack or carry-on suitcase, storage should not be a problem. However, travelers carrying multiple large suitcases may find the available space a bit limited compared to a traditional hotel room.

Since many international visitors were staying at the hotel, it was clear that the staff and facilities were accustomed to handling travelers with luggage.

What Is Provided for Guests

One of the nice things about staying at Nine Hours is that you do not need to bring many essentials with you.

Guests are typically provided with basic amenities such as towels, sleepwear, slippers, and toiletries, making the stay convenient for both domestic and international travelers.

This is especially helpful if you are visiting Japan with limited luggage or staying for only a short period.

The overall concept is very simple: arrive, shower, sleep, and continue your journey the next day. Everything provided supports that minimalist travel experience.

For travelers who value convenience and efficiency, the amenities offered are more than enough for a comfortable one-night stay.

Things Foreign Travelers Should Know

Is English Available?

One thing I noticed during my stay was how international the hotel felt. Since many guests were visiting from overseas, the hotel is clearly accustomed to serving international travelers.

Basic information and instructions are easy to understand, and the check-in process felt straightforward even for guests who do not speak Japanese.

Because of the large number of foreign visitors, I never felt that language would be a major barrier for most travelers staying here.

Can You Bring Large Suitcases?

This is something many international travelers worry about before staying at a capsule hotel.

At Nine Hours Shinjuku-North, the locker area is separate from the sleeping area. During my stay, I found that there was enough space to store one suitcase and one backpack without any problems.

However, if you are traveling with multiple large suitcases, storage may become more difficult. Guests carrying two or more large suitcases may not be able to fit everything inside the assigned locker space.

If you are traveling with oversized luggage or several bags, I would recommend contacting the hotel in advance or speaking with the staff upon arrival. They may be able to suggest alternative storage options depending on availability.

For most solo travelers and backpackers, though, the storage space should be sufficient for a typical trip around Japan.

Tips for a Better Stay

To get the most out of your stay, I would recommend treating Nine Hours as a place to rest rather than a place to spend your entire day.

The hotel works best if you plan to explore Tokyo during the day and simply return to shower and sleep at night. Bringing earplugs can also be helpful if you are a light sleeper, although I personally found the sleeping area fairly quiet.

If this is your first capsule hotel experience, try to approach it as part of the adventure rather than comparing it directly to a traditional hotel room. The experience is different, but that difference is exactly what makes staying in a Japanese capsule hotel memorable.

Pros and Cons of Staying at Nine Hours Shinjuku

What I Liked

Overall, I had a very positive experience staying at Nine Hours Shinjuku-North.

The hotel was clean, modern, and easy to use, even for first-time capsule hotel guests. I also liked the minimalist design, the convenient location, and the international atmosphere created by travelers from all over the world.

The sleep analysis feature was another unique highlight that helped make the stay more memorable than a typical hotel experience.

That said, there is one thing worth mentioning. Because of the capsule hotel layout, noise can sometimes travel between sleeping pods. During the night, I occasionally heard guests moving around, turning over in bed, or accidentally bumping into the walls of their capsules.

This is not really a problem specific to Nine Hours—it is simply part of staying in a capsule hotel. If you are a very light sleeper, bringing earplugs may be a good idea.

What Could Be Better

To be honest, I did not have any major complaints during my stay.

The facilities were clean, the staff were helpful, and everything worked as expected. Since I booked the hotel knowing it was a capsule hotel rather than a traditional private room, the experience matched my expectations very well.

Of course, travelers looking for complete privacy, large personal space, or luxury amenities may prefer a standard hotel. However, for what Nine Hours is designed to offer, I felt it delivered a comfortable and well-organized experience.

Who I Would Recommend It To

I would recommend Nine Hours Shinjuku-North to several types of travelers.

First, it is a great choice for anyone who wants to experience a Japanese capsule hotel for the first time. The modern design and straightforward system make it easy for international visitors to understand and enjoy.

It is also a good option for travelers looking for affordable accommodation in Tokyo without sacrificing cleanliness or convenience.

Another thing I noticed is that the hotel provides Wi-Fi and comfortable common areas, making it suitable for people who need to do some work while traveling. Digital nomads, remote workers, and business travelers can easily spend time working before heading out to explore the city.

If you only need a place to stay for a few nights and want to experience something uniquely Japanese, I think Nine Hours Shinjuku-North is an excellent option. It combines practicality, affordability, and a memorable travel experience in a way that few other accommodations can.

Is a Japanese Capsule Hotel Worth Trying?

Different from Regular Hotels

If you have only stayed in traditional hotels before, a capsule hotel will definitely feel different.

You do not have a private room, and most facilities are shared with other guests. The focus is on providing a comfortable place to sleep rather than offering a large personal space.

At first, I wasn’t sure whether I would enjoy the experience. However, after spending a night at Nine Hours Shinjuku-North, I realized that comparing a capsule hotel directly to a standard hotel misses the point.

A capsule hotel is designed for travelers who value convenience, efficiency, and a unique experience rather than luxury.

A Unique Japan Travel Experience

One reason capsule hotels remain popular with international travelers is that they are something uniquely Japanese.

While other countries have hostels and budget accommodations, capsule hotels offer a completely different concept. Sleeping inside a pod-like space, using shared facilities, and experiencing Japan’s efficient approach to accommodation makes the stay memorable.

During my visit, I noticed that many guests seemed just as interested in the experience itself as they were in finding an affordable place to stay.

For many travelers, spending one night in a capsule hotel becomes a fun story to tell after returning home.

Why I Think It’s Worth Trying at Least Once

Personally, I think staying in a Japanese capsule hotel is worth trying at least once during a trip to Japan.

The experience was comfortable, affordable, and surprisingly practical. More importantly, it gave me a chance to experience a style of accommodation that is strongly associated with Japanese travel culture.

Would I choose a capsule hotel for every trip? Probably not. But for a short stay in Tokyo, a late-night arrival, or simply for the experience itself, I would definitely consider staying at one again.

If you are curious about capsule hotels but unsure whether they are right for you, I would recommend giving them a chance. You may be surprised by how comfortable and enjoyable the experience can be.

The modern design, clean facilities, international atmosphere, and unique sleep analysis service helped create an experience that felt distinctly Japanese while still being comfortable for travelers from around the world.

What stood out most to me was how many international visitors were staying there. It felt less like a traditional hotel and more like a place where travelers from different countries could share a uniquely Japanese experience.

While capsule hotels may not be for everyone, I think Nine Hours Shinjuku-North is an excellent introduction for first-time visitors who want to try one. The concept is easy to understand, the facilities are clean, and the overall experience is much more comfortable than many people expect.
