An AI mobile-plan advisor for Japanese consumers that tracks carrier plan changes (like the ahamo +10GB bump), forecasts your household's data usage, and recommends the cheapest plan across docomo, au, softbank, rakuten, and major MVNOs.
Japanese consumers re-evaluating their mobile plan after a carrier change or promo
- Real-time tracker of carrier plan changes and limited-time promos with push alerts
- Personalized data-usage forecast built from your past bills or a 1-week usage log
- Household optimizer that combines multiple lines into the cheapest bundle across carriers

ahamo is trending at 500+ JP searches after docomo's surprise +10GB jump; consumers are actively re-shopping plans and need a tool that keeps up with weekly carrier news rather than a stale comparison table.
