Japanese companies are increasing their bond sales due to speculation that the Bank of Japan may raise interest rates in December.

KDDI Corp., a major telecom company, issued ¥210 billion ($1.4 billion) in notes across four tranches, with Daiwa Securities Co. as one of the underwriters. Alongside KDDI, eight issuers, including Daiwa Securities Group Inc. and Panasonic Corp., participated in the bond sales on Friday.

This surge in activity reflects a broader trend as companies take advantage of favorable market conditions before potential rate hikes by the central bank.
