In Japan, many of us are feeling the squeeze of rising costs: food, energy, housing, and yes, even mobile phone bills. 2025 is no exception. If you’re looking for a mobile plan that holds its ground, offers genuine value, and keeps your monthly cost stable, then Rakuten Mobile stands out.
Rising Costs and Why Your Mobile Plan Matters
With inflation pushing up everyday prices, it’s smart to look at expenses you can control. Your mobile phone bill is one of them. Traditional carriers in Japan have seen price plans climb beyond ¥7,000 a month for “unlimited” plans. If you’re paying that much, there’s real potential to save.

What Rakuten Mobile Offers in 2025
Rakuten Mobile’s “SAIKYO Plan” delivers several compelling features that show its value clearly:
The base plan starts at ¥980 (¥968 including tax) for up to 3 GB of data in Japan.
For unlimited data usage (within the carrier’s network), the effective fee is around ¥3,278 (tax included), which is far lower than many competitors.
Free overseas data: In more than 90 countries, you get up to 2 GB of data each month at no extra cost.
Additional benefits: Free domestic calls when using the Rakuten Link app; rewards in the wider Rakuten ecosystem (points, shopping, services).
Real Life Applications That Make a Difference
Let’s break down how these benefits play out in real life:
1. Keeping monthly costs predictable Say you use moderate data each month: your fee may stay at the lower tier. With Rakuten Mobile, the ceiling for “unlimited” is far lower than rivals; you can avoid a bill that suddenly jumps because of overage or hidden surcharges. Compare that to a traditional carrier, where you might pay ¥7,000+ per month.
2. Using your phone abroad without extra stress or cost If you travel or spend time abroad, the free 2 GB overseas data means you don’t need to rent a pocket Wi-Fi, buy a local SIM, or worry about massive roaming fees. For modest usage (maps, email, taxi booking) it covers your needs without surprise charges.
3. Leveraging the wider Rakuten ecosystem With Rakuten Mobile, you earn Rakuten Points for your plan and other services. This connects your mobile expense to your shopping, travel and daily life. Over time, your savings compound.
Why This Is Especially Valuable in 2025
Because inflation is impacting more parts of the household budget, stabilising mobile communication costs becomes more strategic. A phone plan that remains fixed or modest while other costs rise is effectively a small hedge. Additionally, as data-use patterns increase (streaming, home working, device usage), having a plan that offers generous data for a low cost becomes more important.

Who Should Consider Switching?
If you’re currently paying more than ¥4,000-¥5,000 per month for your mobile plan and want to reduce costs without sacrificing data or convenience.
If you travel abroad even occasionally (for business or holidays), and want free overseas data.
If you use multiple Rakuten services already (shopping, travel, credit card) and want to weave your mobile cost into that ecosystem.
If you’re sensitive to rising household costs and want one expense you can control.
Things to Check Before Switching
Confirm your device is compatible with Rakuten Mobile’s network (especially 5G and “platinum band” if indoor coverage matters).
Check coverage in your specific area.
Read the campaign conditions for the point bonus to understand timing and requirements.
Decide on whether you will port your number (MNP) or start a new line.
