Pros
- A Huge Catalogue: Around 300,000 tours, activities and attraction tickets across more than 550 cities in over 92 countries, according to its investors' 2026 profiles.
- An Asia Specialist: Founded in Taipei in 2014, KKday is especially strong in Japan, South Korea, Taiwan, Hong Kong and Southeast Asia, where travellers on Tripadvisor's forums often prefer its support to rivals'.
- The Practical Bits Too: Rail passes, airport transfers, car hire and travel SIMs and eSIMs sit alongside the tours, with mobile vouchers and a first-purchase discount in the app.
Cons
- Its Trustpilot score is low at 1.9 out of 5, with complaints about cancellation fees on changed bookings and marketing emails, so check each listing's cancellation terms carefully before paying.
- Cancellation rules are set by each local operator rather than KKday, so double-check names, dates and passport details at checkout, because corrections can mean cancelling and rebooking.
The Verdict
What sets KKday apart is depth across Asia, in one app: KKday was founded in Taipei in 2014 and has grown into one of Asia's largest experience platforms, with around 300,000 tours, activities and attraction tickets across more than 550 cities in over 92 countries, according to its investors' 2026 profiles. Its strength is the region it grew up in: Japan, South Korea, Taiwan, Hong Kong, Thailand, Vietnam and the rest of Southeast Asia, where it lists everything from theme-park tickets and day trips to cooking classes and private drivers. Many experiences are run by local operators, so the reviews on each listing are the best guide to quality. Several travellers on Tripadvisor's Vietnam forum say they prefer KKday to Klook when something goes wrong, praising quick in-app responses and smoother transport arrangements. The practical side is what makes it worth bookmarking. Beyond tours, KKday sells rail passes, airport transfers, car hire and travel SIMs and eSIMs, so one app can hold most of a trip's vouchers, which are scanned on the day. New app users get a first-purchase discount code, though some promotions exclude passes such as the JR Pass and Universal Studios Japan tickets. Cancellation terms are set by each experience and shown on the listing before you pay; many tours allow free cancellation up to a set number of days ahead, while others are non-refundable. For a first trip to Japan or Korea, having the airport transfer, rail pass and day tours in one place saves a lot of tabs and confirmation emails. The reservation is customer service at scale. KKday's Trustpilot score is a poor 1.9 out of 5, with recurring complaints about service fees when a booking has to be cancelled to fix a detail, slow escalations and a steady stream of marketing emails once you sign up. Read each listing's cancellation policy, enter names and dates exactly as on your passport, and unsubscribe from marketing if you prefer quiet; with that care, KKday is one of the most complete ways to book a Japan, Korea, Taiwan or Southeast Asia itinerary in an evening.

About this review
How this was written, who paid for what, and how the verdict stays independent.
Is this KKday review sponsored?
No. KKday did not pay for this write-up, see it before publication, or have any say in the verdict. If we earn anything it is a commission after you buy, and it comes out of the merchant’s margin rather than your price.
How was the KKday assessed?
By using it and by checking the claims made about it against what it actually does. Where our time with something has been limited, the review says so rather than implying more testing than happened.
What else have you reviewed in Travel & Tours?
Everything in Travel & Tours sits in the review library, where you can filter by budget and sort by rating, price or how recently it landed.
Do you update reviews after publishing?
Yes — when a product changes, when a price moves for good, or when we get something wrong. Corrections are made on the piece itself with a note saying what changed.
