Jizo and Dosojin

"Ksitigarbha (Sanskrit Kṣitigarbha, Chinese: 地藏; pinyin: Dìzàng; Japanese: 地蔵; rōmaji: Jizō) is a bodhisattva primarily revered in East Asian Buddhism and usually depicted as a Buddhist monk. His name may be translated as "Earth Treasury", "Earth Store", "Earth Matrix", or "Earth Womb". Ksitigarbha is known for his vow to take responsibility for the instruction of all beings in the six worlds between the death of Gautama Buddha and the rise of Maitreya, as well as his vow not to achieve Buddhahood until all hells are emptied. He is therefore often regarded as the bodhisattva of hell-beings, as well as the guardian of children and patron deity of deceased children and aborted fetuses in Japanese culture, where he is known as Jizō or Ojizō-sama, as a protector of children". (source: Wiki)

"Dōsojin (道祖神, road ancestor kami) is a generic name for a type of Shinto kami popularly worshipped in Kantō and neighboring areas where, as tutelary deities of borders, they are believed to protect travelers and villages from epidemics and evil spirits. Also called Sae no kami or Sai no kami (障の神・塞の神), Dōrokujin (道陸神) or Shakujin (石神, literally: "stone kami"), they are often represented as a human couple, by carved male or female genitals, large stones or statues, or even tall poles along a road". (source: Wiki)
