Good-luck charms in the shape of a heart, which is the same form as the city's geographical features, have been made by Rikyu Hachimangu Shrine in Oyamazaki, Oyamazaki-cho, Kyoto Prefecture. The charms were planned in commemoration of the 1,150th anniversary of the shrine's foundation, in hopes they would become a new local souvenir. The charms are available in two colors, red and purple. They were named "Minori-mamori" with wish that one's efforts and fate will bear fruit.

As the city's geographical shape is the same as a "heart," this word has also been used as the name for local administrative and financial reform plans in the past. The unique shape was thought up in response to visitors' wishes for a small good-luck charms which would also serve as a mobile-phone strap. "Minori-mamori" are all small-sized, three centimeter wide charms. The Chinese characters for "Rikyu Hachimangu Shrine" are stitched with gold thread onto the charm's surface, and a little bell is also attached.

Sadahiro Tsuda, one of Rikyu Hachimangu Shrine's administrators, said, "God is also watching over our efforts toward goals and relations related to our jobs, love and other things. We made them with the hope that various kinds of happiness would bear fruit." The charm is sold for 800 yen.
