Many members of an ōendan will dress in long happi and wear hachimaki emblazoned with team logos, inspirational sayings, or the names of their favorite players, something adopted by some fans of Morning Musume. Especially with professional baseball teams, the ōendan for each team will come up with unique cheers to help the fans become involved. These cheers will often change depending on who the opposing team is. On occasion, the fans themselves will come up with a new cheer that is then adopted by other fans and their team's ōendan.
