The "Why" Behind Sakura Mobile

When you land in Japan, you will see many WiFi rental stalls. However, not all Pocket WiFi services are built the same. Sakura Mobile focuses on the things that matter most to international visitors: Coverage and Communication.

The docomo Advantage: Coverage Where Others Fail

Most rental companies use SoftBank or au networks. We choose NTT docomo. Why? Because docomo is the "Platinum" network of Japan. It has the widest coverage in rural areas and the strongest signal penetration in mountain regions. If you are planning to visit places like Hakone, Takayama, or Hokkaido, docomo is the only way to ensure you aren't stuck without GPS.

English-First Service: No "Lost in Translation" Issues

Many travelers run into trouble when their device has a technical glitch and the support team only speaks Japanese. At Sakura Mobile, we are an English-first company. Our team is available 7 days a week to help you. From the moment you order until the day you return the device, you can communicate with us easily in English.

Built for the Modern Traveler

A travel router is only as good as its performance. Our Pocket Wifi is built to meet the needs of families, business travelers, and content creators.

Unlimited Data: The 10 GB High-Speed Guarantee

Most "unlimited" plans in Japan have a hidden "Fair Usage Policy" (FUP) that slows your speed to a crawl after just 1 or 2 GB.

The Sakura Mobile Difference: We are transparent. We guarantee 10 GB of high-speed data every single day. Even if you use more than 10 GB, we do not cut you off. Your speed may slow down temporarily, but it resets every night at midnight. This is plenty of data for hours of video calls, streaming, and navigation.

The 20-Hour Powerhouse: From Coffee to Ramen

Standard Pocket WiFi units usually die after 6 to 8 hours. Our device is built for long days of sightseeing. With a 20-hour battery life, you can turn it on at your hotel in the morning and it will still be running when you are out for late-night ramen.

15-Device Connectivity: Power for the Whole Group

Traveling with family? One Sakura Mobile device can connect up to 15 devices at once. This includes smartphones, tablets, laptops, and even gaming consoles. While you can connect 15, we recommend staying around 5 devices simultaneously to maintain the fastest speed for everyone.

Why 3,000+ Travelers Choose Us

In 2026, the market for travel internet in Japan is crowded. We know that data speeds and battery life matter, but trust is what ultimately determines your travel experience. Sakura Mobile consistently ranks as a top-tier provider because we prioritize human connection and transparency.

Verified Ratings

We are proud to maintain high ratings across the world's most trusted review platforms:

  • Trustpilot: ⭐4.7/5 (Based on 1,300+ reviews)
  • Google Reviews: ⭐ 4.6/5 (Based on 500+ reviews)

Pricing & Value: Professional Connectivity for Less

We believe that high-quality internet should be affordable. We offer high-speed, quality connectivity without the high-end price tag.

Transparent Daily Rates: 299 JPY

Our pricing starts as low as 299 JPY (approx. $2 USD) per day for longer rentals. There are no hidden activation fees or surprise charges. What you see during the checkout process is exactly what you pay.

The Cost-Efficiency of Group Sharing

Think about the math: If a family of four buys four separate eSIMs, the cost adds up very quickly. By sharing one Sakura Mobile Pocket WiFi, you divide the cost by four. It is the most economical way for groups to stay connected in Japan.

Insurance & Add-Ons for Peace of Mind

Accidents happen. We highly recommend our Insurance Plan for 110 JPY/day. This covers 100% of the cost if the device is lost, stolen, or damaged. For a small daily fee, you can travel without worrying about a large replacement bill.
