What caused Japan’s lost decade?

Japan experienced an unprecedented economic boom in the 1980s known as "The Miracle on the River", however this led to an asset price bubble and overinvestment which caused a stock market crash and real estate bubble burst in 1989. This, combined with structural problems within Japan's economy such as a lack of competition, rigid labor markets, high government debt, and deflationary pressures, resulted in a prolonged period of stagnation throughout much of the 1990s causing significant losses for both individuals and businesses alike.
