Take a cue from electronica duo Air and bring along your “Cherry Blossom Girl” (or guy) to the annual festival celebrating traditional and contemporary Japanese culture at the Brooklyn Botanic Garden. At the two-day Sakura Matsuri (or Cherry Blossom Festival), which starts Saturday, marvel at the beauty of the eponymous fair flower in bloom, enjoy Japanese cuisine, and take your pick of family-friendly day-long activities that include martial arts, manga artists, J-pop, tea ceremonies, a cosplay fashion show and cabaret, bonsai demonstrations, a kids’ origami workshop, sudoku, and anime stand-up comedy. There’s also the BBG Parasol Society Promenade (today at 3 p.m.), which boasts, “Tokyo goth gals, Victorian maidens, and boho Bo-Peeps,” and includes festivalgoers. Nothing like participating in a promenade to put a little extra spring in your step.

Sat., April 30, 10 a.m.; Sun., May 1, 10 a.m., 2011
