What you can do on Kosokubus.com

Compare buses from multiple companies on one screen

Enter your departure point, destination, travel date and number of passengers, and the services of every company operating on that route are shown in a single list. You can sort them by fare, departure time or arrival time to compare.

Daytime buses depart between early morning and night and do not involve an overnight journey. Overnight buses depart between evening and 2:00 a.m. (26:00) and arrive the next morning. You can choose either when searching.

Narrow down by your preferences

Tell us your preferred seat position

When booking, you can submit a preferred seat position using our "Seat Request" feature. Kosokubus.com was the first highway bus portal site to introduce this feature.

Check the bus interior and boarding point before you ride

For some services, we post videos showing the bus interior and the area around the meeting point. You can also read reviews from passengers who have actually ridden each service.

Payment methods

Choose one of the following when booking. Both require advance payment; you cannot pay on the day at the boarding point.

Credit card	DC / VISA / MasterCard / American Express / JCB. You can save up to 5 cards, and from your next booking onward you only need to enter the security code. Payments are processed through the GMO Payment Gateway system.
PayPay	Pay in the PayPay app or on the website.

Receipts can be issued and reissued from My Page after payment. When searching, you can also filter buses by options such as "Credit card accepted" or "PayPay accepted".

Choosing a booking site

There are three main ways to book a highway bus. Which one suits you depends on whether you want to compare fares before deciding or have already decided which bus company to take.

Frequently asked questions

What kind of site is Kosokubus.com?

It is a site for comparing and booking highway buses and overnight buses, operated by Online Travel Co., Ltd. We list more than 3,000 services operated by around 160 companies across Japan, so you can line up services from multiple companies on the same route, compare fares and seat types, and book and pay right away.

How do I find the cheapest bus?

Search by route and date, then sort the results from lowest fare. The top page also shows this weekend's lowest fares by date for major routes departing from Tokyo, Nagoya, Osaka, Fukuoka and Sendai.

Even on the same route, fares tend to be lower on weekdays, for 4-seats-per-row buses and for overnight buses.

How is this different from booking on a bus company's official site?

A bus company's official site shows only that company's services. Kosokubus.com lists services from many companies, so you can compare fares, departure times and seat types on the same route before choosing. Even if you choose different bus companies for the outbound and return trips, you only need to pay once.

Are there buses where women traveling alone can feel safe?

You can filter by three options: "Women-only bus", "Women-only seats" and "Women-friendly". A women-only bus has all seats reserved for women and cannot be booked by men. Women-only seats means some seats on the bus are reserved for women. Women-friendly means the adjacent seat is generally assigned to someone of the same gender.

Can I search only for buses with 3 independent seats per row or a toilet on board?

Yes. You can filter by seat type (2 seats per row, 3 seats per row (2+1), 3 independent seats per row, 4 seats per row) and by facilities (reserved seating, Nobinobi, toilet on board, on-board perks, charging outlets).

Which payment methods can I use?

Credit cards (DC / VISA / MasterCard / American Express / JCB) and PayPay are accepted.

Both require advance payment; you cannot pay on the day at the boarding point.

Can I book in languages other than Japanese?

Yes. In addition to Japanese, the site is available in English, 繁體中文 (Traditional Chinese), 简体中文 (Simplified Chinese) and 한글 (Korean).

Can I change or cancel my booking?

You can cancel from My Page (a cancellation deadline applies). Please note that the travel date and time cannot be changed after booking, so you will need to make a new booking. Cancellation fees vary depending on the bus operator and ticket type.

Enter your departure point, destination and travel date to compare current seat availability and fares.
