Japan's lottery sales have reported a significant slump over the last 20 years, indicating a nearly 30% decrease. While reasons for this stagnation range from lack of interest and an ageing population, regulatory issues have been pointed out as considerable barriers as well. The continual downturn is stirring concerns not only for the lottery industry but also for the public organizations relying on the proceeds for funding.

In Japan, the lottery is more than just a means of entertainment, serving as an important revenue source for public sector organizations. The 30% decrease in lottery sales over the past two decades can be attributed to a combination of factors, such as a shifting economy, changing interests, and an increasingly aging population. In addition, strict regulations regarding advertising and online sales have further stifled growth and innovation in the industry.

In contrast, lottery industries in the US and EU have seen substantial growth thanks to the adoption of online platforms and strategic marketing. More flexible regulations have enabled these regions to capitalize on the demand for such games, adapting to technological and societal changes.
