Trivia

 * The God Tree is similar to both the world tree and the tree of life, motifs that are present in several real-life religions and mythologies throughout the world. In addition, it shares similarities to Jubokko, a yōkai tree that appears on former battlefields and feeds on the blood of humans.
 * The God Tree bearing the fruit that was deemed forbidden to consume is very similar to the story of the Tree of the knowledge of good and evil in Abrahamic religions, in which Adam and Eve, the first humans, ate the forbidden fruit despite being told otherwise. Ultimately, while becoming wiser, it lead to their downfall by incurring the wrath of God. For disobeying Him, He forever cursed the two and their descendants.

A person who smells the fruit can extend his lifespan by 360 years, while a person who eats the fruit can live for another 47,000 years. This served as one of the 81 (9x9) trials that the pilgrims had to endure in their quest to fetch Buddha's Great Vehicle Scriptures (Mahayana/Mahayana sutras).
