Guidelines for this notebook

Thank you for opening Tokyo Osanpo Notebook. Here are a few notes to help you enjoy it.

Your records

  • Your seals and omikuji draws are saved only on your device. They are not sent to me.
  • If you clear your browser data or change phones, your Seal Book is cleared too. Spare Key holders can make a Backup and restore it with a backup code. Backups are kept on the server and can only be opened with that code.

Location data

  • When you stamp a seal, your device's location is used only to check that you are near the spot. Your location itself is not saved.
  • The "Current Location" button on the Station Map uses your location only to show it on the map. It is not saved or sent anywhere.
  • Seal serial numbers are counted with an irreversible hash of your connection, so that you get the same number again. Nobody, including me, can tell who stamped.

Outside services

  • Fonts come from Google Fonts, and the weather on your seal comes from Open-Meteo, looked up by the spot's location, never yours. The hint map uses GSI Japan map tiles. Fetching the map images tells GSI roughly which area is on screen, but your location itself is not sent. To show which way you're facing, the map may use your phone's orientation sensor.
  • Side-trip spots open in Google Maps, and events link to their official sites. Please follow each service's terms.

When you walk

  • Please don't use your phone while walking. Stop before you look for a view.
  • Some spots are shops, shrines, or temples. Please respect opening hours and local manners, and keep your voice down. You never need to enter or buy anything for a seal.
  • Do not enter private property or closed areas. When taking photos, please be considerate of the people around you.

Event and spot information

  • Event dates and shop details may change or end. Please check the official information before you go.
  • Seal photos show the view when they were taken. Seasons or construction may change things, so please bear with us. If a view has changed, tap “Report something about this spot” on the seal card. For anything else, please use the form below.
