Yama

Yama is an old friend of Jinta Yadomi's father and a professional firework maker. He's the one who agrees to make the fireworks in Menma's honor, mentioning that a single one costs around two hundred thousand yen. The next day, however, the group learns he can no longer fulfil the order, after being told to stop by one of Menma's parents.

Yama is an older man, tall with a sturdy build, very short grey hair, and grey eyes. He's usually seen in a white shirt with a breast pocket, worn under a red-and-black kimono, along with dark blue trousers and work boots.
