Japan, Korea or Taiwan: A Complete Guide to Booking Train Tickets on Klook

Planning a trip around Japan, South Korea or Taiwan sounds exciting—until you start figuring out train tickets.

Which train should you choose? Do you need a rail pass? Should you book before arriving? And is an e-ticket enough to board?

For many international travelers, platforms like Klook can make the process easier by bringing different train and rail products into one place. Klook currently offers train and rail-pass options across Japan, South Korea and Taiwan, including KTX and Taiwan High Speed Rail products.

Here’s how to approach your booking without making it unnecessarily complicated.

Japan: When You Need Shinkansen or Regional Train Tickets

Japan is famous for its Shinkansen, but not every journey requires a bullet train.

If your itinerary includes major cities such as Tokyo, Kyoto, Osaka or Hiroshima, a high-speed train may be the most convenient option for certain long-distance routes. Japan also has numerous regional trains and tourist-focused rail products.

When searching for Japan train tickets on Klook, first check:

• Departure and arrival stations
• Travel date and departure time
• Train type
• Reserved or applicable seating options
• Whether a rail pass makes sense for your itinerary

For example, the Tokaido Shinkansen connects major destinations including Tokyo, Kyoto and Shin-Osaka. Official JR information also confirms that online Shinkansen reservations are available for eligible routes.

The important point is simple: don’t automatically buy a nationwide rail pass just because you’re visiting Japan. Compare the actual journeys in your itinerary first.

South Korea: KTX Makes City-to-City Travel Easy

South Korea is particularly straightforward for travelers who want to move between major cities by train.

KTX is the key option for routes such as Seoul to Busan, while other services connect Seoul with destinations including Daegu, Gyeongju, Jeonju and Gangneung. Klook currently lists several of these routes.

When looking for KTX tickets on Klook, enter your departure city, destination and travel date. Then compare the available departures before selecting the one that fits your itinerary.

Klook’s current Korea rail information says eligible tickets can be booked up to three months ahead and that travelers can board using the Klook e-ticket without collecting a physical ticket.

A common mistake

Don’t confuse KTX with every high-speed rail service in Korea. Klook specifically notes that its Korea rail booking does not include SRT, although it covers KTX and several other train types.

So always check the exact train type before paying.

Taiwan: THSR or Regular Railway?

Taiwan gives travelers another useful choice.

If you’re traveling between major cities quickly, Taiwan High Speed Rail (THSR) can be an attractive option. For slower regional journeys and destinations away from the main high-speed corridor, Taiwan Railway may be more appropriate.

Klook currently lists both Taiwan High Speed Rail tickets and THSR passes, while Taiwan Railway has separate booking and ticket-collection procedures.

That means your first question shouldn’t be “Which ticket is cheapest?”

Instead ask:

“Which railway matches my route?”

For example, a traveler planning several high-speed journeys may want to compare a THSR pass with individual tickets. Someone taking a scenic or regional journey may need Taiwan Railway instead.

Klook Train Booking: What Should You Check?

Before clicking the payment button, spend a minute checking these details:

1. Correct stations – Large cities can have multiple stations.
2. Travel date – Make sure the date matches your itinerary.
3. Departure time – Leave enough time if you’re connecting from a flight or another train.
4. Passenger details – Enter names and passport information exactly as required.
5. Ticket type – Check whether you’re buying a single journey, return ticket or rail pass.
6. Seat information – Understand whether seat selection is included or handled differently.
7. Redemption instructions – Don’t assume every country uses the same boarding process.

This last point is especially important because Japan, Korea and Taiwan don’t necessarily handle railway tickets in exactly the same way.

Should You Book Train Tickets on Klook Before Your Trip?

For popular routes and fixed travel dates, booking ahead can make itinerary planning easier.

However, the ideal booking window depends on the railway and ticket type.

For example, Klook’s current Korea rail information allows bookings up to three months in advance, while its Taiwan Railway product has different booking and collection rules.

So don’t use one booking rule for all three countries.

Instead, check the specific product’s availability, cancellation policy, seat information and redemption instructions before purchasing.
