Each September, Tigrayan communities around the world celebrate Ashenda, a vibrant cultural festival honoring young women, music, tradition, and community connection.

Known for colorful traditional clothing, singing, dancing, and joyful gatherings, Ashenda is one of the most beloved celebrations in Tigrayan culture. Following the Filseta fasting season, girls and young women gather in friendship and celebration while communities come together to honor heritage, identity, and shared tradition.

For communities both in Tigray Region and throughout the diaspora, Ashenda has also become a symbol of resilience and cultural continuity—especially after years of conflict and displacement.

In Denver, the celebration offers an opportunity to strengthen community bonds, share cultural traditions with younger generations, and deepen understanding through music, food, storytelling, and fellowship

 Fall in Love with Japan

This is not a traditional tour.

The Denver Takayama Sister City Committee invites you to experience Japan through the relationships built over more than sixty years of friendship between Denver and Takayama.

Travel alongside fellow Denver-area participants as you explore historic cities, ride Japan’s famous Shinkansen bullet train, enjoy authentic regional cuisine, and experience the warmth of local hospitality. Most importantly, you’ll gain a deeper understanding of Japan through the unique lens of Denver’s official sister-city partnership.

Whether this is your first visit to Japan or a return journey, this exchange offers cultural access and local connections rarely available through conventional travel programs.
