垜
垜 is a word that means a target or mound when shooting an arrow with a bow.
Actually, it is pronounced as “amututi'' or “shada'', which is a combination of two kanji characters as 射 and 垜,
but considering that a photo studio is a place for shooting, 射 which means shoot, is not necessarly.
Instead, 射 is complemented as a space, and it is read as [amututi] with just 垜.
