Dressed up in kimonos and their respective countries' Sunday best, young adults from various countries attended a diverse Japanese coming-of-age ceremony hosted by Tokyo's Shinjuku Ward on Jan. 14.

The young adults represented countries including Malaysia, Uganda, Madagascar, Brazil, China, South Korea, Canada and France.

Their presence shows that the myth of a “homogenous” Japan no longer applies, at least to Shinjuku Ward, where one in every two new adults is a foreign national.

"I am very excited,” an American woman and her female friend from Mexico, both decked out in "furisode" long-sleeved kimono, said at once.

Ami Tanaka, born in Shinjuku to a Filipino mother, said, “I want to go back to the Philippines to tell my grandmother there that I turned 20.”

Some 4,109 new adults reside in Shinjuku Ward, of which 1,868, or about 45 percent, are foreign nationals, according to the ward office.

Foreigners account for just over 10 percent of the total population of the ward. But there are many colleges and Japanese language schools in Shinjuku, and a large number of foreign students turn 20 this year. These are contributing factors to such a high ratio of foreign nationals among new adults, the ward office said.
