The price of a senior car (electric wheelchair) is approximately 150,000 to 500,000 yen for a new one, and 50,000 to 200,000 yen for a used one. While maintenance costs are relatively low, the maximum speed is 6 km/h, and in principle, they are limited to sidewalks. For those who want to expand their range of movement, specified small mopeds, which are in the same price range, can also be considered.

Senior Car Price Range
| Category | Approximate Price Range | Features |
|---|---|---|
| Entry Model | 150,000 - 200,000 yen | Simple configuration for short distances |
| Standard Model | 200,000 - 350,000 yen | Enhanced with features like batteries and shopping baskets |
| High-end Model | 350,000 - 500,000 yen or more | Supports long-distance travel and high-functional equipment |
While used items may be found at lower prices, it is necessary to check for battery degradation, warranty status, brake and safety device operation, and availability of replacement parts. Do not judge solely by the purchase price; consider future repair costs as well.
Maintenance Costs and Pre-Purchase Considerations
Senior cars can be charged with household outlets, and the annual electricity cost is approximately 2,000 to 4,000 yen. Compulsory automobile liability insurance and vehicle inspections are not required, but battery replacement may cost about 20,000 to 50,000 yen every 2 to 3 years.
- Can you test ride at a dealer or showroom?
- Do you have storage space at home or in a garage?
- Can you secure a charging outlet?
- Are sidewalks maintained on the roads you usually use?
- Can you request inspections and repairs after purchase?
Limitations of Senior Cars
Senior cars are designed as mobility aids for those with difficulty walking. Therefore, the maximum speed is 6 km/h, which is similar to walking speed. Additionally, they cannot be driven on roadways, and may be inconvenient on roads without sidewalks. While convenient for short-distance shopping or doctor visits, they may be insufficient for those who wish to travel slightly further.
Specified Small Mopeds as an Option
Specified small mopeds, established in July 2023, are electric mobility devices that can be ridden without a driver's license by those aged 16 or older. Like senior cars, they do not require a license, but their maximum speed is 20 km/h, and some models can switch to a 6 km/h sidewalk mode. While obtaining a license plate and compulsory automobile liability insurance are necessary, the significant difference is their ability to expand your range of activity.

Summary
Senior cars are suitable for short-distance travel for those with walking difficulties. On the other hand, if you can walk independently and want to expand your range of movement for doctor visits, shopping, or daily travel, a specified small moped is also a strong option. Compare not only the price but also the speed, driving location, storage environment, and support system to choose the one that suits your lifestyle.
