20-year-olds are celebrating coming-of-age ceremonies across Japan today (Monday).

20 is the age when Japanese youths become full legal adults.

Some of them celebrated the national holiday by climbing a 60-story building in Osaka.

At almost 1,000 feet, the new Abeno Harukas building is Japan’s tallest.

Thousands of new adults also partied at Tokyo Disneyland.

Mickey and friends congratulated them on taking up the rights and responsibilities of adulthood.
