Despite major stock sell-off, Jesper Koll of Monex Group is ready to begin purchasing Japan.

• On Monday, Jesper Koll, head of Japan at Monex Group, revealed to CNBC that he is ready to take the first step and begin investing in Japan.
• The country's financial stability is not a concern, as Japanese fundamentals are "solid," he stated.
• On Monday, Japan's Nikkei 225 experienced its largest daily decline since 1987's "Black Monday," amounting to a 12.4% drop.

Despite a major stock-sell off in Japanese markets on Monday, Monex Group's Jesper Koll is prepared to "start buying Japan" based on the country's solid fundamentals.

Although the movement of the Japanese yen may cause earnings to be revised downwards, there have been improvements in corporate governance, capital stewardship, an investment drive, and increasing real estate prices, according to Koll. He stated that the fundamentals in the country are "actually much, much more solid" on CNBC's "Squawk Box Europe" on Monday.

Koll, head of Japan at Monex Group, stated that he is ready to take the first step and begin investing in Japan.

On Monday, Japan's Nikkei 225 experienced its largest daily drop since 1987's "Black Monday," falling 12.4%. This decline has discouraged some investors, with Kelvin Tay, the regional chief investment officer at UBS Global Wealth Management, advising caution earlier on Monday, stating that entering the Japanese market now would be like catching "a falling knife."

The Japanese Finance Minister, Shunichi Suzuki, stated that the government was collaborating with the central bank and closely monitoring financial market fluctuations with "serious concern." Suzuki also mentioned that foreign exchange rates were being closely monitored by authorities.

The yen's 38-year low against the U.S. dollar in July prompted authorities to intervene and strengthen the yen, according to data from Japan's Ministry of Finance. A stronger yen can negatively impact Japan's stock markets.

Last week, the Bank of Japan raised its benchmark interest rate to its highest level since 2008 and announced plans to reduce its purchase of Japanese government bonds following the intervention.

Japan's banking system is well capitalized and has limited exposure to global market gyrations, according to Monex Group's Koll, who stated that he was "not at all" concerned about financial stability in the country.

"Unlike in the United States, Japan's unemployment rate will continue to decline due to the growth of domestic business investment expenditure, making it recession-proof. This will eventually have a positive impact on capital markets in Tokyo," he stated.
