B-Daman (ビーダマン, Bīdaman) is a marble shooting toy franchise produced in Japan by Takara.
Different attachments and accessories can be used to change various traits of the B-Daman, such as its accuracy, power, balance, control, and firing rate.
In the Japanese language Battle B-Daman toys, the marbles are referred to as "B-Dama".
In all cases they are simply called "marbles" (Japanese: ビー玉; bīdama, hence the name "B-Daman") in Japan.
In the English language B-Daman toylines and media, the marbles were originally called 'B-DaBalls", but was later changed to "B-DaMarbles" for safety reasons[citation needed].
This series shares the majority of its themes and design language with B-Daman, but uses plastic screw caps instead of marbles.
Some of the toys included in the series are directly based on B-Daman figures and characters, with appropriately updated names.
