Why do the same airwaves cost ¥7,000/mo on Docomo and ¥3,278/mo on Rakuten?
No "winner" — both, not the cheaper. Question, not answer.
Providers — price + speed + image-value
Each row: 1-line social-mirror commentary.
| Provider | Monthly | Speed | Image-value |
|---|---|---|---|
| NTT ドコモ (eximo) | ¥7,315 | — | State-incumbent DNA — synonymous with reliability |
| au (KDDI / use) | ¥7,238 | — | KDDI brand — life-design positioning |
| SoftBank | ¥7,238 | — | Early iPhone exclusivity — self-defined as the innovator |
| ahamo / povo / LINEMO | ¥2,970 | — | Big 3's online-only sub-brands — same airwaves, half price |
| 楽天モバイル | ¥3,278 | — | Japan's fourth carrier (2020) — symbol of unlimited data |
Quality (objective) vs Image (value-proof)
Two axes — separated, not blended.

Marketing strategy
Big 3 lock customers in via retail stores, carrier email, family discounts. Newer/online-only brands (ahamo, povo, LINEMO, Rakuten) compete on price and simplicity. Net effect: half-off — but only for those who switch.
Social mirror
What price gap reveals about the society.
In 2020 PM Suga publicly called Japanese mobile bills 'too high', and within a year every carrier launched half-price plans. A price the market couldn't reach for two decades, politics moved in twelve months.
Try both — same airwaves, different brand philosophies.
Prices reflect 2025 standard plans. Family discounts, device bundles, and promotions can shift the actual amount.
