Just a little bit, but Osamu is kind of thinking along those lines. He just clicks with Hanamaki.

He walks over to the stand, hands over the omamori he got last year and buys a new, then moves over to the next stall to write his wishes for the next year on the traditional paper. 'Good fortune for my business and for my brother'

Once it's dry, he twists it up and waits for Hanamaki to finish up and join him to tie their prayers to the tree.
