Hello, I’m Rational Travel, a travel blogger who doesn’t do sponsored content and only tells the truth . When you travel to Japan and get tired from walking, popping into Starbucks for a coffee is a standard itinerary for many people. But do you always dutifully pay full price and watch your Japanese yen disappear?  

What if I told you there’s a public secret, a money-saving hack that almost all tourists don’t know about, that lets you enjoy another extra-large Starbucks cup for less than 30 Taiwan dollars, and you can even add chocolate or caramel sauce for free? Wouldn’t you feel like you’ve been missing out big time?

Today, Rational Travel is going to reveal this “hidden menu” and teach you how to unlock this insider hack that only hardcore players know, so next time you go to Japan, you can enjoy coffee the smartest way.

As always, before we start the article, let me introduce myself, since not everyone knows who I am.

Subscribe to Rational Travel and put strategies in your pocket

Rational Travel’s honest take: I usually send flight deals and other money-saving hacks to subscribers first, and only publish them publicly after some time, so subscribers get a head start to grab them. After all, many of these have time limits and quantity restrictions, so it’s only fair to give subscribers first access.

If you’re used to buying and selling miles or snagging last-minute hotel deals in Facebook groups, Rational Travel recently launched the ‘Easy Ticket Platform – use now, pay later with platform escrow‘ free for subscribers.

P.S. Subscribers not only get complete strategies but also enjoy lifetime fee-free status on the Easy Ticket Platform.It’s free now—when I start charging, who knows. So you get it. We currently have close to 2000 subscribers (throwing confetti happily).
