Throw your two dishes at the torii gate. If your dish goes under the torii gate, your wish will come true. Geez, look at all those failed wishes (shattered dishes).

This is also one location where the film Idai Naru, Shurararabon (偉大なる、しゅららぼん The Great Shu Ra Ra Boom) was filmed. The scene where Ryosuke throws his small dish through the torii.
