Assumptions behind these numbers
- Model assumptionStart charge 100%, arrive with 15% in reserve, charge up to 80% at each stop.
- Model assumptionUsable battery: 100% of each vehicle's listed capacity (the listed capacity may be gross or net; no correction is applied).
- Model assumptionSpeed: consumption starts from each vehicle's listed real-world efficiency, times a speed factor of 1.00 (1.00 = no speed adjustment).
- Vehicle dataWeather: each vehicle uses its own hot, normal and cold factor from our vehicle data, so consumption = efficiency x 1.00 / factor. Hot is 25 °C and above, normal is 10-25 °C, cold is below 10 °C.
- Model assumptionCharging speed: average power = min(vehicle peak kW, 150 kW cap) x 0.60 taper, plus 5 min per stop.
- MethodRange, energy and cost all use the same consumption figure. Energy is measured at the battery; charging losses are not included.
- MethodCharging stops are estimated from range and the charging window. They are not verified charging stations.
- Market dataCost: not shown, because no electricity market price is available for Japan.
- Market dataCO2: energy x grid average carbon intensity of 407 g/kWh (Japan, Ember Climate, Monthly average, March 2026, older than 45 days, last available value).

The 1,165-kilometre drive from Tokyo to Kumamoto, with a drive duration of 903 minutes, presents a substantial but well-supported journey for an electric vehicle. The route is not cross-border, remaining entirely within Japan, and both cities experience a normal climate, which avoids significant battery range reduction from extreme temperatures. Practical planning should account for at least one or two longer charging stops, as the distance far exceeds the typical real-world range of most EVs. The normal climate and flat terrain likely associated with this corridor mean range estimates will be reliable, but drivers should still verify station availability in the final leg to Kumamoto to avoid last-minute range anxiety.
