japannese group

when I heard about the nature of the Japanese people are always true to the time, I was a little less take notice. until I was able to climb from the Japanese group are very punctual when climbing.
although they are slow moving, but they will try to meet the time while climbing up to the summit. caused slow to reach the summit, the group still wants to continue and was quite surprised when they fall over, they just take a break for 10 minutes and back down again.
sound like something crazy right?
