Answer 1

On Children's Day in Japan they use a symbol like this:

Here is a quote from the below source explaining it "Gogatsu ningyo (5th Month Dolls) are displayed in homes and store windows with images of Kintarou, usually riding on a large carp, and a traditional Japanese samurai helmet, a Kabuto. Kintarou and the Kabuto are both symbols of a strong and healthy boy. Kintarou (金太郎) is the childhood name of a hero of the Heian period, famous for his strength as a child. It is said that Kintarou mounted on a bear, instead of a horse, and played with animals in the mountain when he was a young boy."
