Tired of overpaying for gas in Japan? GasoNavi shows how much each station beats the national average. Price forecasts, route search for cheapest stops, 30,000+ stations. Stop guessing. Start saving on every fill-up. GasoNavi shows you exactly how each gas station compares to the national average -- so you always know where the deals are, even when prices fluctuate. Finding cheap gas in Japan shouldn't be this hard. Prices change weekly, vary wildly by area, and member discounts make it even more confusing. GasoNavi cuts through the noise: see at a glance which stations are consistently cheaper, get next week's price forecast, and find the cheapest station along your route before you even leave home. --- What GasoNavi Can Do --- FIND CHEAP GAS INSTANTLY Search over 30,000 stations across Japan on an interactive map. Every station displays its price difference from the national average (e.g., "5 yen below average"), so you can spot the best deals without memorizing prices. Filter by fuel type -- regular, premium, or diesel. CHEAPEST STATION ALONG YOUR ROUTE Planning a drive? Enter your destination and GasoNavi finds the cheapest station along the way -- no detours needed. One tap launches navigation in Google Maps, Apple Maps, or Yahoo! Car Navi. PRICE FORECAST -- KNOW BEFORE YOU FILL Will prices go up next week or drop? GasoNavi's weekly price forecast helps you decide whether to fill up now or wait. Never regret filling up the day before a price drop again. FUEL LOG & EXPENSE TRACKING Log every fill-up and GasoNavi automatically tracks your fuel economy, spending trends, and cost-per-kilometer -- all visualized in clean charts. Your fuel log doubles as a price report to help other drivers, with zero extra effort. Need records for tax filing? Export your fuel history as CSV anytime. MEMBER PRICING SUPPORT See member prices for ENEOS, apollostation, Cosmo, and other major brands. Compare what you'll actually pay, not just the posted price. AREA PRICE RANKINGS Check which stations rank cheapest in your area. Great for discovering new go-to stations when you move or travel.

A fun bonus for road-trippers and completionists. --- All Features --- - 30,000+ gas stations across Japan - Price comparison vs. national average for every station - Cheapest-along-your-route search - One-tap navigation (Google Maps / Apple Maps / Yahoo!
