Is this a dendrobium?
 

It has canes, so thats what I'm guessing it is.

Nobile.

Thanks guys :)

Dend. Nobile--nice one.

It's probably a hybrid with D. nobile ancestry. At the Yamamoto Orchids Web site you can read how to care for them. They are easy to grow, but have some specific needs to be met in order to flower.

Edit June 15 2020:
Yamamoto Dendrobiums in Japan hybridizes and produces a great number of these plants. Their Web site formerly had excellent growing information for hobbyists. Unfortunately it is no longer there. You can still look at the varieties they grow, and maybe see one very similar to yours.

I saved the page, and summarized it in a post in this thread:
Uncertain if Dendrobium is still alive

Yamamoto now has a page showing how to force Dendrobium nobile for Christmas flowering in Japan's climate. There is a lot to learn from that page, but it is intended for growers who can artificially heat and cool their greenhouses during off seasons. Note they use coconut husk for growing medium, which many orchidists would say retains too much water for orchids. For many orchids that is correct, but this is a very thirsty orchid.
