However, reports from South Africa on Monday said the 55-year-old had already put pen to paper on a two-year contract worth 5 million rand ($385,563) per year with the Cape Town-based Stormers.
The reports also suggested Jones could retain his role with Japan despite being based out of South Africa.
Jones told Japan's Kyodo News on Tuesday he was simply exploring his options.
"I am chatting with (the Stormers) but that's the extent of it," he said. "I am off contract in 2015 and I'm looking at my options.
"Players and coaches sign contracts and do everything they can until the contract comes to an end. But you need to look elsewhere when your contract is coming to an end. That's professional rugby."
Jones, who has never held a top coaching position in South Africa, said he was always drawn to the appeal of doing something different.
"That's why I came to Japan after coaching in England," he said.
"No Australian has done anything in Japan. I like new challenges and that's why I am chatting with them."
The Stormers lost to Australia's Brumbies in the playoffs of this year's Super Rugby tournament.
Their coach, Allister Coetzee, has since moved to Japan to take over Top League side Kobe Kobelco Steelers.
