Quick Answer: povo 2.0 is Japan's most flexible mobile plan — a ¥0/month base with data purchased as-needed "toppings." It runs on au/KDDI's network. Ideal for users with variable data needs: pay only for what you use. The trade-off: the topping system requires more active management than a fixed monthly plan, and toppings have expiration dates.
How povo's Topping System Works
Unlike traditional plans, povo 2.0 starts at ¥0/month with 128 kbps connectivity (enough for basic messaging). You then purchase "toppings" — data packages that activate immediately:
| Topping | Price | Validity | Per-GB Cost |
|---|---|---|---|
| 1GB | ¥390 | 7 days | ¥390/GB |
| 3GB | ¥990 | 30 days | ¥330/GB |
| 20GB | ¥2,700 | 30 days | ¥135/GB |
| 60GB | ¥6,490 | 90 days | ¥108/GB |
| 150GB | ¥12,980 | 180 days | ¥87/GB |
| Unlimited (24h) | ¥330 | 24 hours | — |
The 24-hour unlimited topping (¥330) is particularly useful for travel days, downloading large files, or weekend streaming sessions.
What We Like
- True flexibility — Some months you might use 1GB, others 20GB. Pay accordingly instead of a fixed monthly fee.
- au's network — Strong coverage nationwide, particularly good in suburban areas and mountains.
- ¥0 base plan — Can serve as a "standby" number at zero cost, as long as you purchase at least one topping every 180 days to keep the account active.
- 24-hour unlimited — ¥330 for a full day of unlimited data is excellent for occasional heavy usage.
- 150GB/180 days topping — At ¥87/GB, this is among the cheapest per-GB rates available in Japan for quality network access.
- eSIM support — Quick activation available.
What Needs Improvement
- Complexity — The topping system is unfamiliar to most people. Forgetting to buy a topping means you're stuck at 128 kbps.
- Toppings expire — Unused data doesn't persist beyond the topping's validity period. If you buy 3GB/30 days and only use 1GB, the remaining 2GB is lost.
- No voice plan included — Voice calls are ¥22/30 seconds unless you add a 5-minute calling topping (¥550/month) or unlimited calling topping (¥1,650/month).
- Account maintenance rule — You need to purchase at least one topping every 180 days, or your account may be deactivated.
- Online-only, Japanese-first — No store support. Interface and support are primarily in Japanese.
Foreign Resident Experience
Sign-up: Online, primarily in Japanese. Requires Residence Card and Japanese credit card (debit cards and bank accounts not supported for some payment methods). The eKYC process is standard.
Day-to-day: The povo app handles topping purchases and usage monitoring. It requires some active management — you need to remember to buy toppings before they expire.
Who Should Consider povo 2.0
- Tech-savvy users who enjoy optimizing their costs
- People with highly variable monthly data usage
- Users who want a secondary/backup phone number at minimal cost
- Those who occasionally need bursts of heavy data (use the 24h unlimited topping)
Q: What happens if I don't buy a topping for 180 days?
Your account may be suspended and eventually deactivated. To keep povo active at minimum cost, purchase at least one small topping (e.g., 1GB/¥390) within every 180-day window.
Q: Can I stack multiple toppings?
Yes. If you buy a 3GB topping and then a 20GB topping, both are active and data draws from the one expiring soonest. You can also buy the 24h unlimited on top of an existing data topping.
Q: Is povo cheaper than LINEMO for light users?
It depends on usage pattern. If you consistently use around 3GB/month, LINEMO's ¥990 Mini Plan is simpler and equivalent. If your usage varies — some months near zero, others 10GB+ — povo can be cheaper overall since you only pay for what you use.
