The communal worship that tanzaku (long, narrow card) cards on which a wish is written are hung up on small bamboos provided on the right and left sides of the kaya grass hoop and the bamboos are thrown into a river on the Tanabata festival corresponds to the event in which kakizome (New Year's writing, resolution) is burnt in the Dondon-yaki (a Shinto blessing of objects that have been a part of a celebration but are now debris consuming by fire from the 14th to the 16th of the lunar New Year) to improve writing.
また、茅の輪の左右に設置する笹竹に願い事を書いた短冊を振下げ、七夕に河川に流すといった俗信仰は、書初めをどんどん焼きで焚くと筆が上達するといった行事と対応している。
