Planning Assumptions
Purpose
Capture reusable assumptions that help plan Japan-related work without re-answering the same basics.
When to Use
Use this page when a request needs a starting point but does not yet require detailed itinerary, language, or city research.
Assumptions
- Start with rail-first planning unless the request is explicitly rural, luggage-heavy, mobility-constrained, or time-sensitive enough to justify taxis or driving.
- Plan days around one primary anchor, one secondary option, and one nearby fallback. Japan itineraries degrade quickly when every day assumes perfect transfers, no queues, and unlimited walking.
- Keep arrival and departure days light. International travel, immigration, luggage, jet lag, and unfamiliar transit make those days poor candidates for fixed-ticket attractions.
- For cities, choose lodging by transit access before neighborhood aesthetics. A slightly less charming stay near the right station can beat a prettier stay with awkward transfers.
- Assume reservations matter for popular restaurants, museums, theme parks, seasonal events, ryokan meals, and limited-seat trains. Verify booking windows before treating a plan as locked.
- Separate stable preferences from live facts. Stable: traveler constraints, interests, pacing, dietary restrictions. Live: prices, timetables, closures, baggage rules, weather, festivals, and entry requirements.
- Keep addresses in both English/romaji and Japanese when possible, especially for taxis, lodging, and emergency use.
Gotchas
- Do not treat snapshot assumptions as current for bookings, opening hours, pricing, or legal requirements.
- A plan that works on a map may fail with stairs, luggage, heat, rain, crowds, or missed limited-express connections.
