Well that was to be expected. Golden week is one of the longest vacations the Japanese get. On April 29 they have Shōwa Day to commemorate the emperor, on May 3 they have the Constitution Memorial day, on the fourth Greenery day and on the fifth (my birthday LOL) they have Kodomo no hi = Children's day.
Instead of just taking those days off, they decided to put it into a week long vacation *shrugs* A lot of people go travelling then. It's a very popular vacation in Japan
So yeah, it makes sense that Kishimoto-sensei would take a little break too
