Right off the bat, if you’re a high-maintenance traveler, then this article isn’t for you. However, if you’re a solo female traveler searching for a budget-friendly hotel in Tokyo, then read on! Like many big cities, finding affordable accommodation can be challenging. When I traveled to Japan during the Sakura high season, hotel prices skyrocketed during this popular time. However, I discovered a budget-friendly gem that offered both comfort and convenience: 9h Nine Hours Woman Shinjuku Capsule Hotel. If you’re a solo female traveler looking to stretch your dollar while exploring Tokyo, this review will help you decide if this unique accommodation option is right for you.

What Is a Female Capsule Hotel in Tokyo?

The best way to describe a capsule hotel is like staying at a hostel, but a level up. It’s perfect for travelers who prioritize location and budget over luxurious amenities. I had heard about capsule hotels in Tokyo before my trip, and I decided to book a two-night stay just for the plot. Ironically, the same morning I checked in here, I had checked out of a 5-star luxury hotel in Taiwan just hours before.

As a capsule hotel near Shinjuku Station, 9h Nine Hours Woman Shinjuku provides excellent access to the vibrant Shinjuku area and popular districts like Shibuya. There are several 9h Capsule Hotels throughout Japan, with most being co-ed, but a few remain exclusive to women. This is one of the only women-only capsule hotels in Tokyo, and that’s the main reason I booked. Even though Japan is a relatively safe country, I still prefer to opt for a women-only environment when possible. I stayed in a couple of mixed-dorm albergues when I hiked the Camino de Santiago, and it was not for me. No ma’am!

Capsule Hotel Self-Service Check-In Process

Check-in is quick and easy through a self-service kiosk. Apparently, with Japan being an introvert haven, this is ideal so that there’s limited human interaction. Personally, I prefer talking to someone for my check-ins, but if you encounter any issues, staff members are available on-site until midnight to assist you.

Upon check-in, you’re assigned a locker that only fits a carry-on-sized suitcase. I had a check-in-sized suitcase, so it couldn’t fit, and I had to leave it outside the lockers. While this might concern some travelers, I wasn’t worried about theft – it’s Japan, after all, a high-trust society. My Japanese cousin once told me a story about how she lost her engagement ring on the metro, but she wasn’t even worried. She knew she would find it at the lost and found. That being said, obviously, I kept my valuables with me.

Sleeping in a Pod at a Women-Only Capsule Hotel in Tokyo

The original sleeping pods at 9h Nine Hours are crafted from Fiber Reinforced Plastic (FRP) and feature a soft, cocoon-like design that eliminates any industrial feel. The pods are surprisingly spacious and create a reassuring environment.

Each pod comes equipped with:

• Power outlet and USB-A charging port
• Adjustable lighting with a dimming controller
• Roller shade for privacy
• High-quality mattress, pillow, and duvet
• Motion sensors and infrared cameras for sleep monitoring

The mattress and duvet are 9H’s original models created in collaboration with Nikke Shoji. The mattress strikes an excellent balance between softness and firmness, while the duvet provides optimal warmth for a cozy sleep experience. According to their website, the pillow is a “Gymnast Plus” model by Makura no Kitamura, specially resized to fit the sleeping pods. Its unique structure is divided into eight sections, each made from a different material, designed to support natural movements during sleep.

Amenities and Facilities at a Capsule Hotel in Tokyo

Every day, guests receive:

• Fresh pajamas
• UCHINO long pile bath and face towels
• Slippers
• Toothbrush and toothpaste

The shower and bathroom facilities feature private shower stalls and toilets with bidets. The shower products are from the original ‘Tamanohada’ brand, a product from the Tamanohada Soap Company. Their signature 005-FIG model features a simple, fragrant formula with non-silicone shampoo for a gentle cleanse.

The Sleep Monitoring System at Nine Hours Woman Shinjuku Capsule Hotel

One “unique” feature of 9h Nine Hours is their sleep analysis model called “9h sleep fitscan.” This system supposedly measures sleep quality by collecting guest data using infrared cameras, microphones, and motion sensors. The pod’s shape, which envelops your body 360 degrees, enables advanced sensing without additional devices.

After your stay, you receive a sleep report detailing metrics such as heart rate, snoring, and instances of apnea. While this provides interesting insights into your sleep patterns, I couldn’t find a way to opt out of this monitoring. Why this is included as a feature of staying here is quite sus to me. Depending on your comfort level, this could potentially be a deal-breaker.

The Social Atmosphere

One thing I noticed during my stay at this Tokyo capsule hotel for women was the diverse mix. All ages and ethnicities were represented. Despite the communal setup, everyone is quiet and minds their own business. Most guests appear to be solo travelers who travel frequently and prioritize stretching their dollar over luxury. However, I think many are also local Japanese who may have missed the last train of the night and just needed somewhere to sleep until the trains started again. Either way, it’s nice to have a budget-friendly space to spend the night.

Pros and Cons of Nine Hours Woman Shinjuku Capsule Hotel

Pros:

Would I Stay at Nine Hours Woman Shinjuku Capsule Hotel Again?

Overall, my stay at 9h Nine Hours Woman Shinjuku Capsule Hotel was a positive experience, and I’d stay again if necessary. I paid $95 for two nights, which breaks down to $47.50 per night. By simply signing up and making an account online, you get an extra 10% off your stay. That’s solid since I wasn’t planning to be inside most of the day and was out exploring Tokyo. If you’re a solo female traveler who prioritizes location and affordability over luxury and privacy, this capsule hotel experience is worth considering. Just pack earplugs, plan your shower schedule strategically, and embrace the unique experience of sleeping in a high-tech pod in one of the world’s most exciting cities.
