2. What is Fiber-Optic Internet?
First, let’s start with fiber-optic internet. Fiber-optic or fiber internet uses cutting-edge technology to transmit data through ultra-thin glass cables.
Fiber offers a stable, wired connection that is faster and more reliable than traditional broadband.
See our table below to compare the pros and cons of fiber internet, and what Sakura Mobile has to offer.
Pros👍 | Cons👎 |
|---|---|
| Ultra-fast speeds: 1 Gbps or up to 10 Gbps (with Sakura Mobile). | Installation required: It can take from 1 week to 1 month to set up.** |
| Low latency: Perfect for gaming, streaming, and remote work.* | Fixed location: Not as portable as home WiFi. |
| Unlimited data: Ideal for heavy internet users. | May not be feasible: Shared housing or certain apartments may not support fiber installations. |
*Latency is the time it takes for data to pass from one point on a network to another.
**Sakura Mobile provides support for negotiations in Japanese (ex. confirming installation details with your property manager).
Don’t worry! Sakura Mobile offers rental pocket WiFi to keep you connected while your fiber installation is underway.

3. What is Home WiFi?
Next, let’s look at home WiFi. This option connects your home to the internet using cellular networks (4G/5G). A wireless router receives the signal and broadcasts it as WiFi, providing flexible connectivity without complex installation.
See our table below to compare the pros and cons of home WiFi, and what Sakura Mobile has to offer.
Pros👍 | Cons👎 |
|---|---|
| Simple set-up: Just plug in and go (with Sakura Mobile’s Home WiFi device). | Less stable than fiber: Speeds can vary depending on network conditions and location. |
| Relocation-friendly: No installation required, ideal for short-term residents. | May experience higher latency |
| Fast speeds, unlimited data, and coverage over most of Japan | More likely to be impacted by bad weather conditions |

4. Comparing Speeds
When choosing an internet plan, understanding speed requirements is key to making the right decision.
The chart below highlights the recommended speeds for common online activities.
Activity | Recommended Speed |
|---|---|
| 4K Video Streaming/Online Gaming | 25 Mbps |
| Online Meetings | 10 Mbps |
| HD Video Streaming (1080p) | 5 Mbps |
| Web Browsing/Emails/Messaging Apps | 1 Mbps |
See the connection speeds for fiber internet and home WiFi below! ⬇️
🌸Our fiber internet uses Flet’s Hikari fiber-optic network by NTT, the largest network provider in Japan.
To sum up the speed differences between fiber and home wifi:
- Fiber Internet: Consistent, symmetrical speeds; perfect for heavy uploads or multiplayer gaming.
Up to 1 Gbps / 10 Gbps.* - Home WiFi: High-speed 4G/5G connection, but performance can fluctuate depending on signal strength and usage.
For the fastest speeds, fiber is your go-to option. On the other hand, if you aren’t a heavy-data user and flexibility is your priority, home WiFi may suit you better.
*Maximum network service capability speed for Fiber. Depending on your residence, the line type may be between 10 Gbps and 100 Mbps. After applying, we will look into your location and options to determine what the line/speed will be.

✈️ Your Priority: Flexibility and convenience.
If you’re new to Japan, frequently moving, or only here for a short time, home WiFi is the solution for you. It’s quick to set up, portable, and doesn’t require installation, making it perfect for short-term residents or frequent travelers.

Scenario 3
Scene: You just got a new job that lets you work from home — yay! Your partner is also working remotely. Now school is on vacation and your kid is at home streaming YouTube videos on their phone and Netflix on the TV.
→ You notice that having so many devices using the internet simultaneously — running Zoom meetings, streaming movies, etc. — is seriously slowing down your connection.
🏡 Your Priority: High capacity for multiple users and devices.
If everyone is streaming, gaming, and working simultaneously, you’ll need the unlimited data and high speeds of fiber internet.
💡 Recommendation: Opt for Sakura Mobile’s Fiber Internet to handle the demands of a busy household.
But what if your family is smaller or you share WiFi with only a few roommates? In that case, Home WiFi can be a practical alternative. Home WiFi offers a hassle-free solution with sufficient speed for everyday streaming, browsing, and casual gaming.

Paulo B. ☺️
Oct 16, 2024Transparent Service with Excellent Support
I have both mobile phone service and fiber internet, and both provide consistently excellent connection and signal. I use the home fiber for gaming, which demands a top-notch connection. I’ve never had any issues, and customer service has always been fantastic— it genuinely felt like I could reach out to a friend with any questions.

Sep 24, 2024Sakura is a must for any foreigners!
I’m a new ALT in Japan, with minimal Japanese so I needed a company with reliable coverage and good English support. My office’s ethernet was too slow, and I was relying on my pocket WiFi too much for home and work, so I signed up for their fibre package. The support was immaculate. Within a week of requesting the Fibre, I had my device shipped to me and set up.So trust me, if you’re looking for great connection, great speeds, and fantastic coverage, then Sakura is your best bet!

September 21, 2024Highly recommended, easy ordering process
We purchased Sakura mobile’s home 5G internet for our vacation home in Japan. Sakura mobile was very easy to order online and the unit arrived quickly. Setup was simple and instructions were easy to follow. They also took online credit card payment for monthly fees and did not require residency.
