Berkshire Hathaway CEO Greg Abel said that none of the five Japanese trading houses his company has stakes in has noted the country's record-high interest rates as a "fundamental challenge."

"I think they see it as very manageable," Abel told CNBC from Japan, where he is currently traveling.

Berkshire has north of $15 billion worth of outstanding yen-denominated debt, according to its latest quarterly report. Abel said he still sees raising debt in Japan as an appropriate strategy.

Japan's 10-year government bond yield hit 3.01% on Wednesday, its highest level in about three decades.
