Thunder Drum

The Thunder Drum (風袋, Fūtai) is a famous tool used by ninja given the position of Raijin just like the Wind Bag is used by the ninja given the position of Fūjin. It is a circle of drums, held together by a halo, the drums act as generators of lightning, having no limit, the wielder has to introduce their own chakra into the bag to utilise the chakra from the drums to generate lightning chakra from the drums. The lightning from the bag is a unique being that it's colouration is black and is considered to be much more powerful than that of regular Lightning Release.

The halo and drums are connected to its user's body through a form of passive and invisible chakra thread, if they are cut new chakra threads will be created to replace them. This is because the wielder must synchronise their chakra with the Thunder Drum and this is only if the ninja is compatible. The halo has nine drums in total around it and are activated by a trigger in the form of drumsticks, this is the counterpart of the Wind Bag's openings. This involves them being a master of Lightning Release and to come from the Tenjin clan.

In recent years the Wind Bag and Thunder Drum has become affiliated with Takegakure due to the Tenjin clan joining the village.
