Scope: EV-fleet TCO at a Japan hotel destination-charging site · Entity: 1 EV vs 1 ICE vehicle · Horizon: 25 years · Discount rate: 8.00% · Evidence date: 2026-09-22 · Limitation: EVSE hardware cost and Japan certificate numbers are out of scope of the scenario model and are not included in the TCO figures below.
This page reports the TCO of replacing one ICE vehicle with one EV in a hotel shuttle / courtesy-car role in Japan, over a 25-year horizon at an 8.00% discount rate. The EVSE itself is not modelled; the scenario books EVSE CapEx and OpEx at zero and only values the fleet operating-cost delta.

The figures on this page are produced by the scenario model for the explicit bounded scenario below. Every line is presented as a model assumption, not a sourced fact. Re-running the model with different bounded assumptions will change every reported number; the COMPUTED TABLES below are the computed figures for the scenario defined here.
