Buddhism is distinct from other religions, but if you mean it co-existed with other religions in different cultures, then you are correct.
I think Buddhism was repressed in Japan before the conquest of Asia, and the aggressive imperialism of japan had much more to do with the cult of the Emperor and Shinto.
But the Buddha stated clearly that Nirvana was the fall of all Karma in the pursuit of happiness, and that there was not a bit of reincarnation in Nirvana but rather a state of wakefulness. Yet, a lot of interpretations endorse reincarnations and heavens.
Reincarnation is part of the Buddhist philosophy. You are correct to state that Buddhism is the pursuit of happiness - usually referred to as the ending of suffering. This is achieved through the attainment of Nirvana - Enlightenment - which results in an ending of the cycle of birth death and rebirth - reincarnation. It's not the case that reincarnation has been endorsed when it had been denied by the Buddha. The aim is to end reincarnation though.
Also in stories of The Buddha, he ascends to various heavens. These do not resemble Judeo-Christian concepts of eternal heavens, but are filled with beings who are still subject to samsara and will eventually be reborn into a lower rebirth when the good karma that helped them there runs out. this kind of existence, whilst being considered fortunate, is not as fortunate as a uman rebirth, as the distractions are too great for the beings to commit to a spiritual path.
Many nihilistic nontheless.
This is incorrect. The Buddha taught The Middle Way between the extremes of eternalism and nihilism. Anything that advocates nihilism can't be described as Buddhism.
