With International Women's Day right around the corner, YouTube launched its #DearMe campaign, encouraging women to reflect on their past and post video messages with advice to their younger selves. The project became the No. 1 trending topic on Twitter within an hour after its launch.

YouTube recruited a range of women from a variety of countries, backgrounds and professions, including blogger Grace Helbig, actress Felicia Day and the band Pentatonix. The selection also included many women living in Japan. Here are a few of the #DearMe videos highlighted by YouTube.
