The 20 Hour Mistake: What AI Got Wrong About My Client’s Trip to Japan
“When AI Takes the Wrong Turn”
Last fall, I received a last minute request for a two week trip to Japan from some of my top clients. Before they came to me, they did what a lot of curious travelers do first. They asked ChatGPT to build the itinerary.
The image above is what the AI suggested for their 14 days.
While AI is great for some things, this suggested itinerary was absolutely insane. My clients would have spent roughly 20 hours in the car over the course of their two week trip, navigating a country with road signs in Japanese, an international driver's license requirement, unfamiliar traffic laws, and narrow rural roads that challenge even confident local drivers. It was a recipe for chaos.
Why the AI Plan Fell Apart
On paper, the itinerary looked ambitious and full. In reality, it was built by something that had never stood in a Tokyo train station, never watched a client's face light up at their first bowl of ramen in Kyoto, and never had to rebook a missed connection in real time.
A few of the problems I spotted immediately:
The driving was completely unnecessary. Japan has one of the finest rail networks in the world, and for most of the routes the AI proposed, the train is faster, calmer, and far more scenic than a rental car.
The pacing was punishing. Long transfers were stacked on back to back days with no room to actually enjoy any single destination.
The logistics ignored reality. Luggage forwarding, seat reservations on limited express trains, and regional passes were nowhere to be found, and those small details are exactly what make or break a trip.
What a Human Advisor Does Differently
When I plan Japan, I am not just filling in boxes on a calendar. I am thinking about how a day actually feels. I know which ryokan is worth the splurge, which neighborhoods reward an unhurried morning, and how to sequence cities so my clients arrive relaxed rather than exhausted.
Instead of 20 hours in a rental car, my clients will glide between cities on the Shinkansen, watch Mount Fuji slip past the window, and step off the train with their bags already waiting at the next hotel. That is the difference between a trip that looks good in a chat window and a trip that feels effortless in real life.
AI can generate an itinerary in seconds. It cannot anticipate the closure that would have derailed day six, or know that a certain guide will make all the difference, or read the quiet cues that tell me what my clients truly want. That judgment comes from experience, relationships, and genuine care.
The Takeaway
Technology is a wonderful starting point, and I am the first to celebrate the things AI does well. But your once in a lifetime trip deserves more than a plausible guess. It deserves someone who has been there, who has the relationships on the ground, and who is accountable to you when things go sideways.
If you are dreaming of Japan, or anywhere else, let's build something that actually works. No 20 hour car rides required.
