Be Happy Koi no Yajirobee

Be Happy Koi no Yajirobee (BE HAPPY 恋のやじろべえ) is the 8th and final single by the Hello! Project girl group Tanpopo, and the first and only release by the group's "third generation" (Rika Ishikawa, Ayumi Shibata, Asami Konno, and Risa Niigaki). It was released on September 26, 2002 with the catalog number EPCE-5178. The first pressing came with a special trading card. The single peaked at #5 on the weekly Oricon charts, charting for 6 weeks. The single has a "crisp feel", with a touch of hip hop and R&B.

This single sold 40,070 copies in its first week and 60,450 copies all together, making it the group's lowest-selling single. It was not, however, their worst-charting single, as it cracked Oricon's top five, which some "first generation" singles had failed to do. The PV for the song was featured on Tanpopo Single V Clips 1, released in June 2004.
