Ichibata Yakushi Kyodan is a religious group found in Japan. They follow the teachings of Yakushi Nyorai, who is the Buddha of Healing.
Imagine you get a cold and you are feeling really unwell. You go to a doctor who gives you some medicine to make you feel better. Now, in the same way, Yakushi Nyorai is believed to be a doctor who can heal all kinds of illnesses and troubles in life.
The members of Ichibata Yakushi Kyodan go to temples to pray to Yakushi Nyorai and ask for his guidance in their lives. They also participate in Buddhist rituals and ceremonies.
It is important to remember that there are lots of different religions and beliefs in the world, and Ichibata Yakushi Kyodan is just one of them.
