How much does the Toyota bZ4X (Z, AWD) cost to own in Japan?

The Toyota bZ4X (Z, AWD) starts at ¥5,500,000. Own it for 5 years in Japan and it comes to about ¥6,020,240 — ¥100,337 per month, or ¥151 per km — including depreciation, charging, maintenance, insurance, shaken inspection and automobile tax, and financing. As of 2026/07/01.

CEV補助金 (national CEV purchase subsidy), FY2026: up to about ¥850,000 from the national government (METI / Next Generation Vehicle Promotion Center) when you buy a new EV — the amount varies by model and by how far the manufacturer supports charging infrastructure and servicing. Plug-in hybrids get a reduced amount; hybrids and petrol cars do not qualify. The budget is capped and applications can close partway through the fiscal year. There is a mandatory holding period (in principle 4 years) — sell early and you may have to repay the subsidy. Not every buyer or model qualifies — which is why we show the subsidy separately and have not folded it into the totals above. Source: METI / Next Generation Vehicle Promotion Center (NeV), as of . Check eligible models and the remaining budget before you buy.
