Established on this date by the Tokyo Chamber of Commerce and Industry due to the pun with the expression "a long and steady walk"!

Long and steady (walk) → tekuteku → teku(teku) → te (short for the English reading of 10) ku (9)

Alright, you've been doing nothing but playing games

We're going on a walk! A walk!

It is recommended to go on a walk without a clear destination in mind, just enjoying walking around to wherever your curiosity may take you!
