天地 tenchi means Heaven and Earth. 開閉 kaihei means to open and to close or to turn on and off (a switch or something). 開 kai means to begin or to evolve/pioneer and 閉 hei means... can you guess? Correct: to end or to close. I really dunno how to translate it as a whole, since it probably has a deeper meaning I don't know of. But my guess is Opening and Closing of the Cosmos, since 天地 can refer to the cosmos or the universe, too. Seelentau 愛 07:51, November 30, 2011 (UTC)

I was kinda hoping for a technique name, similar to when you translated "Hiding in Scale Power Technique". Omnibender - Talk - Contributions 20:09, November 30, 2011 (UTC)
I know, but this one is harder to translate, since it's not a common name, but just a row of Kanji. It's the same with Shinra Tensei, for example. But as I said, it could be translated as Opening and Closing of the Cosmos/Universe. Seelentau 愛 15:43, December 1, 2011 (UTC)
