Why verification matters
We fact-checked the AI-generated Tokyo itinerary
Ask a chatbot for a 3-day Tokyo plan and you'll get confident, plausible text — with closed venues, impossible timing and guessed dietary claims. Here's the failure pattern, and how a human-verified catalog prevents each one.
Try it yourself: ask any chatbot for "a 3-day Tokyo itinerary" and check each venue's official page. The five failures below show up over and over — not because the models are careless, but because fluent text and verified facts are different things.
1. It recommends places that no longer exist
The AI itinerary
AI itineraries still send travellers to Shinjuku's Robot Restaurant (closed since 2021) and to watch the tuna auction at "Tsukiji's inner market" — which moved to Toyosu in 2018. The text is fluent; the place is gone.
A language model reproduces the internet's most-written-about version of Tokyo, and the most-written-about version is years old. Nothing in the generation step checks whether a venue still operates.
The verified catalog
Every place in the tabi catalog is a real, currently-operating venue with a verified native name and address, with volatile facts on a quarterly re-verification schedule. A closed venue is removed — it cannot appear in a plan.
2. It books your museum day for the day it's closed
The AI itinerary
The classic pattern: "Day 2, Monday — morning at the museum." Most Japanese museums close on Mondays; Kanazawa's 21st Century Museum, Tokyo National Museum and many others follow exactly that rule. The Ghibli Museum adds advance-lottery ticketing on top.
Opening rules are structured facts (weekday calendars, holiday shifts, last-entry times). Chatbots emit them as prose, and prose doesn't get cross-checked against your actual travel dates.
The verified catalog
tabi's engine schedules against per-weekday opening hours stored on every place. If your dates put a stop on its closing day, the engine doesn't place it there — and volatile hours carry a visible "verify opening hours" caution.
3. Its days don't survive contact with geography
The AI itinerary
Eight neighbourhoods in one day, "a quick 5-minute hop" between Shibuya and Asakusa (it's ~40 minutes across the city), dinner at 22:30 after a "sunset" viewpoint in December (sunset is 16:30). Plausible on paper, impossible on foot.
Distance, transit time and daylight are numbers. Text generation optimizes for a satisfying-looking list, not for a feasible route through space and time.
The verified catalog
Plans are built one neighbourhood per day with a gapless, timed timeline: transit estimates between every stop, dated weekday-aware days, and inter-city legs (Shinkansen, flights) placed with real durations.
4. It guesses about your dietary needs
The AI itinerary
"Vegetarian-friendly ramen shop" — with a pork-bone broth. "Halal izakaya" — with no certification and alcohol in every sauce. For dietary travellers these aren't inconveniences; they're deal-breakers discovered mid-meal.
Dietary facts are exactly where confident-sounding text is most dangerous: the model has no way to distinguish a menu that says "vegetarian option" from a blog post that assumed one.
The verified catalog
Dietary and accessibility fields in the catalog are verified-only and three-state: true and false require evidence (a menu, a certification, an official page); unknown stays unknown — and an unknown is never shown as a yes. Filter for vegetarian and every meal in your plan is menu-checked.
5. It ignores that half of Tokyo now needs a reservation
The AI itinerary
teamLab, Shibuya Sky at sunset, the Ghibli Museum, popular omakase counters — AI itineraries list them as walk-ins. Several sell out one to four weeks ahead; Ghibli runs a monthly lottery.
Booking pressure changes month to month. A model trained on years of travel writing averages over eras when walk-ins worked.
The verified catalog
Ticketed places are flagged (ticket required, typical visit length), plans carry booking notes on exactly the stops that need them, and your PNRs live next to the plan — offline.
What "verified" means here
tabi plans are assembled from a hand-curated catalog — currently 15 Japan cities and 489 places — where every entry carries a real native name and address, per-weekday opening hours, and evidence-backed dietary and accessibility facts. An AI never picks a place; it can only sequence places that already passed verification. Volatile facts (hours, closures, payment) sit on a quarterly re-verification schedule, and every plan works offline.
