- Worth noticing
- The site says it omits figures it cannot confirm on an official page, and labels numbers with their source and check date.
Field notes
The listed tools accept practical trip inputs: rail legs, origin and destination stations, room rate, nights, guest count, or luggage size. The guide section adds airport connections for Narita, Haneda, and Kansai, alongside regional pass comparisons and child-fare rules. A dated change log separates items marked scheduled from one marked in effect; the homepage also discloses affiliate relationships.
