Using Car-Sharing Services like Times Car

Why Car-Sharing Beats a Rental Car for Most Students

If you've ever needed a car for a quick IKEA run, a weekend hike outside the city, or an airport pickup, you've probably looked at traditional rental agencies and winced at the price. Car-sharing services like Times Car Share, Careco, and Orix Car Share solve this exact problem for students: instead of renting for a minimum of 24 hours, you can book a car for as little as 15 minutes, pick it up from an unmanned parking lot a few blocks from your apartment, and pay only for the time you actually use. No counter, no paperwork each time, no waiting in line — you unlock the car with an IC card or your smartphone and drive off.

This guide walks through exactly how membership works, how to locate and reserve a car near you, and why the math almost always favors car-sharing over conventional rentals when you're a student living on a budget.

How Car-Sharing Actually Works

Car-sharing platforms operate a network of small, unstaffed parking spaces (called "stations" or "ports") scattered throughout residential neighborhoods, near train stations, and inside convenience store lots. Each station has one or two vehicles permanently parked there. You reserve a car through an app, walk to the station, tap your membership card or phone on the windshield reader to unlock the doors, and drive.

Key differences from a rental car company:

• No staff interaction required — everything is self-service, 24 hours a day.
• Billing is by the minute or by 15-minute blocks, not by the day.
• Cars stay parked near residential areas, so you rarely need to travel far to reach one.
• You return the car to the same station you picked it up from (round-trip only, in most cases).
• Fuel and basic insurance are included in the time-based fee — you don't pay separately unless you use significantly more fuel than average.

Because the car is already sitting in a nearby lot rather than at an airport or a central rental office, the entire process — from opening the app to driving away — usually takes under five minutes once you're a member.

Becoming a Member: What You Need and How Long It Takes

Signing up is the only part of the process that takes real advance planning, since approval isn't always instant. Here's what's typically required for the major providers:

Important note for exchange students: International Driving Permits are only valid for driving in Japan if issued in a country party to the 1949 Geneva Convention (this includes the US, UK, Canada, Australia, and most EU countries). Students from countries like China, Vietnam, or Indonesia, which are not signatories, generally need a Japanese driver's license instead — check your home country's status before assuming an IDP will work.

The application itself takes about 10–15 minutes online. Times Car and Careco both ask you to upload photos of your license and residence card, and approval typically arrives within 1–3 business days by mail (they send an IC membership card) or instantly if you're approved for app-only access. Because of this lag, apply at least a week before you actually need a car — don't wait until the night before a trip.

Finding and Reserving a Car Near Your Apartment

Once you're registered, the app becomes your main tool. Here's the typical reservation flow:

1. Open the app and it shows a map of nearby stations with real-time availability.
2. Tap a station to see the car model, fuel type, and current price per 15-minute block.
3. Select your start time (can be immediate or scheduled hours/days ahead) and estimated return time.
4. Confirm the reservation — the car is locked to you for that window.
5. Walk to the station, tap your card or phone on the reader mounted on the windshield or dashboard.
6. The doors unlock and the key is inside the vehicle (often in the glovebox or a fixed holder).
7. Drive, then return to the exact same spot before your reservation ends.

Most major providers have dense networks in cities like Tokyo, Osaka, Nagoya, and Fukuoka — it's common to find a station within a 5–10 minute walk of a university dormitory or apartment. In smaller cities or rural areas, coverage is thinner, so it's worth checking the app's map before committing to an apartment location if you plan to rely on car-sharing regularly.

A few practical tips for finding cars efficiently:

• Popular stations near stations and universities book up fast on weekends — reserve 2–3 days ahead for Saturday trips.
• Filter by car type in the app if you need a larger vehicle (minivans and light trucks are less common and cluster in different stations than compact cars).
• If your default station is full, most apps show the next 3–5 nearest alternatives with live availability.
• You can extend a reservation from your phone if the car is free afterward — no need to physically return and re-check-out.

Pricing Breakdown: 15 Minutes vs. a Full Day

This is where car-sharing becomes dramatically more student-friendly than traditional rentals. Traditional rental companies charge per calendar day (usually 24 hours) even if you only need the car for two hours, and most require a minimum one-day booking. Car-sharing charges you only for the time slots you actually reserve.

The pattern is clear: car-sharing wins big for short trips — anything under about 6 hours — because you're not forced into a full-day rate. Traditional rentals only become competitive once you need the car for close to a full day or longer, and even then, most car-sharing plans offer a "6-hour" or "12-hour pack" rate that narrows the gap. If you need a car for multiple consecutive days (like a road trip), a traditional rental agency or a car-sharing provider's multi-day package is usually cheaper than stacking daily car-share rates.

Also factor in:
- No fuel costs with car-sharing — it's built into the per-minute rate (as long as you don't drive an unusually long distance).
- No insurance upsell pressure — basic compensation coverage is included, though an optional daily "worry-free" surcharge (¥330–550/day) reduces your deductible in case of an accident.
- No return-to-different-location fees since round-trip is standard — factor this in if you were hoping for one-way drop-off, which car-sharing generally does not support.

Comparing the Major Providers

If you're deciding which service to join, here's how the big three stack up for a typical student:

You don't have to pick just one — many students register with two providers (commonly Times Car and Careco) since membership fees are usually credited back as driving time, so there's little downside to joining more than one network if it widens your access to nearby cars.

Practical Tips for First-Time Student Users

A few things that aren't always obvious the first time you use these services:

• Check the fuel gauge before returning. Most providers ask you to refuel if the tank drops below a certain threshold (often 1/4 tank), using a card kept in the vehicle — you won't pay out of pocket, but forgetting can trigger a penalty fee.
• Report damage immediately through the app, even minor scratches, since you're compared against the last documented condition.
• Late returns are penalized heavily — often double the normal per-minute rate — because the next user may be waiting. Set a phone alarm 15 minutes before your reservation ends.
• Smoking is prohibited in nearly all shared vehicles, with cleaning fees around ¥33,000 if violated.
• Some university towns have discounted student plans — check with your international student office, as several providers run partnerships that waive the registration fee for enrolled students.

Once you've got your membership card in hand, car-sharing turns "I wish I had a car right now" into something you can act on in under ten minutes — without the commitment, cost, or paperwork of a traditional rental. For students juggling a tight budget and infrequent driving needs, it's one of the most convenient parts of daily life in Japan.
