The Nikkei, up 57 percent this year, has further to climb in 2014 because of Japanese Prime Minister Shinzo Abe's policies, Dennis Gartman said Monday.

"Abenomics is going to be working. I think you're going to end up seeing economic activity in Japan picking up rather dramatically," he said. "But the most important thing is the weakness of the Japanese yen is going to have a very, very strong impact upon Japanese equities."

"So, I want to be long of the Nikkei. I want to be short of the S&P, one against the other. At the same time, I want to be short of the Japanese yen against the English-speaking currencies," he said, adding one of his oft-repeated plays, "I want to own gold in yen terms."

Basically, he said, "it is one large short-the-yen trade."
