Week
Use a scooter to travel the circumference of the world and it will take you a full week. Seven whole days!

If you want to scoot for a week, you'll need shoes (しゅう). Good shoes too, not sandals or high heels or boots. Solid, high quality shoes, so you don't fall off the scooter and hurt yourself.
An update is needed before you can continue but you have more than one WaniKani tab open.
Finish up what ever you are doing on the other tab(s), then close them to continue.
The update will complete automatically once the other tab(s) are closed.
