Berkshire Hathaway Inc. is exploring a multi-tranche yen bond sale, according to sources. The potential deal, which could include seven different maturities from three to 30 years, follows a recent ¥300 billion ($1.8 billion) investment in insurer Tokio Marine Holdings Inc. The conglomerate aims to price the bonds as early as April 10, with Mizuho Securities and BofA Securities managing the sale. This move signals continued Berkshire's deepening Japan exposure, building on equity stakes in Itochu, Mitsubishi, and Mitsui. The ¥300 billion investment in Tokio Marine represents a significant commitment to Japanese assets.
