Lexus IS maintenance and running costs
The Lexus IS is a luxury car, so you should expect maintenance and running costs to be high.

Lexus IS automobile tax: 43,500 yen (1 year)
Applying this to the table, the gasoline-powered 2.5L inline-4 engine found in the Lexus IS350h and the hybrid version has a 2.5L inline-4 direct-injection engine (Dynamic Force Engine) plus a motor (2.0L or more but less than 2.5L) displacement, so the automobile tax amount is 43,500 yen.
| Engine displacement | Automobile tax amount |
|---|---|
| 660cc | 10,800 yen |
| 1,000cc or less | 25,000 yen |
| More than 1,000cc but less than 1,500cc | 30,500 yen |
| More than 1,500cc but less than 2,000cc | 36,000 yen |
| More than 2,000cc but less than 2,500cc | 43,500 yen |
| More than 2,500cc but less than 3,000cc | 50,000 yen |
| More than 3,000cc but less than 3,500cc | 57,000 yen |
| More than 3,500cc but less than 4,000cc | 65,500 yen |
| More than 4,000cc but less than 4,500cc | 75,500 yen |
| More than 4,500cc but less than 6,000cc | 87,000 yen |
| Over 6,000cc | 110,000 yen |

Voluntary insurance premium: Approximately 100,000 yen (1 year)
Voluntary automobile insurance is insurance that car owners and users can voluntarily purchase to cover the portion of their insurance that is not covered by compulsory automobile liability insurance, or to prepare for damages that are not covered by compulsory automobile liability insurance . The main differences between compulsory automobile liability insurance and voluntary automobile insurance are as follows:
| item | Compulsory automobile liability insurance | Voluntary insurance |
|---|---|---|
| Join | compulsion | any |
| Coverage | Personal injury and property damage compensation | Personal injury and property damage compensation, vehicle insurance, passenger insurance, etc. |
| Compensation amount | minimum level | Subscriber’s choice |
| Insurance premiums | Depends on the vehicle type and age | Depends on the compensation |
Voluntary insurance mainly covers three types of coverage :
- Third-party liability insurance: Covers damages to the other party who is killed or injured.
- Property damage insurance: Covers damage to the other party’s property, such as vehicles and buildings.
- Vehicle insurance: Covers repair costs if your car is damaged in an accident.
You can freely combine these types of coverage to choose the coverage you need. The premium for optional insurance is determined by the coverage you choose, the type of car you own, your age, your accident history, and other factors.
This time, you can freely combine options, and the amount varies depending on the voluntary insurance company, so we think it will cost around 100,000 yen per year, including vehicle insurance.
Compulsory automobile liability insurance (17,650 yen for 2 years) required at the time of vehicle inspection
When purchasing a car, you pay the insurance premium for the period until the next vehicle inspection. The amount of automobile liability insurance premium differs between standard cars and light cars, and when purchasing a new standard car, it costs 17,650 yen.
Standard car: Automobile weight tax (weight tax) levied every two years (32,800 yen for two years)
Since it is a statutory fee that is included in the vehicle inspection fee, it will be listed in the vehicle inspection fee. The automobile weight tax amount is determined by vehicle model. The vehicle weight of the Lexus IS is 1,690kg to 1,720kg, and private passenger cars are inspected every two years, while cargo vehicles are inspected annually.
| Vehicle weight | Less than 13 years since new registration |
|---|---|
| Less than 500kg | 8,200 yen |
| 1,000kg or less | 16,400 yen |
| 1,500kg or less | 24,600 yen |
| 2,000kg or less | 32,800 yen |
| 2.500kg or less | 41,000 yen |
| 3,000kg or less | 49,200 yen |

A word from the editorial department
So far, we’ve focused on price, but we’d like to discuss comfort as well. If comfort is a priority, we recommend a hybrid vehicle. This is because hybrid vehicles offer better fuel economy and motor assistance than gasoline models, allowing for a more relaxed driving experience. Furthermore, they already feature the same engine and hybrid system that has been well-received in many models, including the RAV4, Harrier, Crown (crossover), and Camry. The IS model boasts increased engine and motor output, providing even greater comfort. Annual maintenance costs are estimated to be around 340,000 to 470,000 yen. It’s important to consider these points when making your purchase.
