国債（こくさい、kokusai）
- government bond

The Japanese word 国債, pronounced こくさい (kokusai), refers to government bonds. These are debt securities issued by a national government to raise money. Essentially, when a government issues 国債, it is borrowing money from investors. In return, the government promises to repay the principal amount, along with interest, at a specified date. Think of it like a loan the government takes out. 国債 are a crucial tool for governments to finance public spending, such as infrastructure projects, social programs, and covering budget deficits. They are considered relatively safe investments as they are backed by the full faith and credit of the issuing government.
