Trying to build an exercise habit,
but keep quitting?

  • No time to stick with it...
  • Hard to stay motivated alone
  • Intense workouts aren’t for you

  • It’s not your fault—you just didn’t have the right method yet.

Japanese walking—proven by science—
matched to your fitness.

Alternate three minutes of brisk walking with three minutes of easy walking. Shinshu University research shows this can improve strength and endurance far more than walking at one pace.

Arujikan suggests Japanese walking for your age and fitness level. Voice guidance lets you focus on your walk without staring at the screen.

Why Japanese walking?

  • Increase strength by up to 10%
  • Increase endurance by up to 20%

Effects you won’t get from walking the same pace—backed by research.
