YamaRaja
The Vedic Yama, with certain changes of function, was the basis for the Buddhist Yama, judge of the dead, who presides over the Buddhist Hells. The Buddhist Yama became an integral part of Chinese and Japanese mythology. Although ultimately based on the god Yama of the Hindu Vedas, the Buddhist Yama has developed different myths and different functions from the Hindu deity.
Yama's abode
Naraka (Hindu)
Main article: Naraka (Hinduism)
Naraka in Hinduism, is compared to the Abrahamic concept of Hell. However, Naraka in Hinduism is not equivalent to Hell in Christian faith. Naraka is only a purgatory where the soul gets purified of sin by sufferings. In Hindu myth, there are many hells, and Yama, Lord of Justice, sends human beings after death for appropriate punishment. Even Mukti-yogyas (souls eligible for mukti or moksha), and Nitya-samsarins (forever transmigrating ones in Dvaita theology) can experience Naraka for expiation.
Naraka (Buddhist)
Main article: Naraka (Buddhism)
Naraka is usually translated into English as "hell" or "purgatory". A Naraka differs from the hells of western religions in two respects. First, beings are not sent to Naraka as the result of a divine judgment and punishment; second, the length of a being's stay in a Naraka is not eternal, though it is usually very long. Instead, a being is born into a Naraka as a direct result of his or her previous karma (actions of body, speech and mind), and resides there for a finite length of time until his karma has exhausted its cumulate effect.
Di Yu (Chinese mythology) and Jigoku (Japanese mythology)
Main article: Di Yu and Jigoku
Chinese Di Yu, Japanese Jigoku, literally "earth prison", is the realm of the dead or "hell" in Chinese mythology and Japanese mythology. It is based upon the Buddhist concept of Naraka combined with local afterlife beliefs. Incorporating ideas from Taoism and Buddhism as well as traditional religion in China, Di Yu is a kind of purgatory place which serves not only to punish but also to renew spirits ready for their next incarnation. Jigoku is similar, with Shinto concepts. These names are interchangeable with the concept of Naraka.

Yama and Ymir
Main article: Ymir
In a disputable etymology, W. Meid (1992) has linked the names Yama (reconstructed in Proto-Indo-European as *yemos) and the name of the primeval Norse frost giant Ymir, which can be reconstructed in Proto-Germanic as *umijaz or *jumijaz, in the latter case possibly deriving from PIE *ym̩yos, from the root yem "twin". In his myth, however, Ymir is not a twin, and only shares with Yama the characteristics of being primeval and mortal. However, Ymir is a hermaphrodite and engenders the race of giants.
Yama in Iranian mythology
Main article: Jamshid
The parallel character in the Iranian mythology of Zoroastrianism is known as Yima Xšaēta in the Zoroastrian scripture of the Avesta. The pronunciation "Yima" is peculiar to the Avestan dialect; in most Iranian dialects, including Old Persian, the name would have been "Yama". In the Avesta, the emphasis is on Yima/Yama's character as one of the first mortals and as a great king of men. Over time, *Yamaxšaita was transformed into Jamšēd or Jamshid, celebrated as the greatest of the early Shāhs of the world.
Yama in Javanese
There is Yamadipati in Javanese culture, especially in wayang. The word adipati means ruler or commander. When Hinduism first came to Java, Yama was still the same as Yama in Hindu myth. Later, as Islam replaced Hinduism as the majority religion of Java, Yama was demystified by Walisanga, who ruled at that time. So, in Javanese, Yama became a new character. He is the son of Sanghyang Ismaya and Dewi Sanggani. In the Wayang legend, Yamadipati married Dewi Mumpuni. Unfortunately, Dewi Mumpuni fell in love with Nagatatmala, son of Hyang Anantaboga, who rules the earth. Dewi Mumpuni eventually left Yamadipati, however.
