Japan built the first stablecoin rules, so why is the US moving faster?

Japan was the first country to introduce a formal rulebook for stablecoins. When lawmakers passed the framework in 2022, it looked like Japan was setting the pace for the rest of the world. The rules were strict, focused on consumer protection, and aimed at making sure every stablecoin in circulation was fully backed and transparent.

Yet just a few years later, it seems the United States is racing ahead. New proposals, high-profile legislation, and market enthusiasm are pushing the US into the spotlight. So how did the US pull in front when Japan had such an early lead?

One answer is priorities. Japan’s approach prizes stability above all else. Regulators wanted to build guardrails that would minimize risk for consumers and avoid shocks to the financial system. That meant moving carefully, rolling out rules step by step, and requiring banks or licensed entities to handle stablecoin issuance.

The US, by contrast, is leaning into speed and market opportunity. Lawmakers and regulators are signaling they want to attract innovation, even if it means taking on more short-term risk. This openness has encouraged more companies to experiment with stablecoins, more investors to pay attention, and more policymakers to treat them as a serious part of the future financial system.

As Takashi Tezuka of Startale Group put it: “Japan prizes systemic stability above innovation speed, while the US is signaling a bigger market-opening play.” That single sentence captures the tension well, safety on one side, growth on the other.

This difference reflects culture as much as policy. Japan often takes a cautious stance in financial regulation, prioritizing long-term stability. The US has a history of letting markets innovate quickly, then stepping in with rules once activity has already grown. Neither approach is necessarily right or wrong, but the outcomes are different.

The US now looks set to host a much larger share of stablecoin projects, exchanges, and financial partnerships. That could mean more influence over how global standards are shaped. Japan, meanwhile, may risk falling behind in terms of innovation, even though its framework is seen as one of the safest and most reliable.

For everyday people, the outcome will affect how stablecoins can be used in daily life. If the US dominates, consumers might see faster product rollouts and more options for payments, savings, or cross-border transfers. If Japan’s model wins out globally, stablecoins might spread more slowly but with tighter protections.

In the end, both approaches may shape the market together. Japan’s strict standards could inspire global trust, while the US push for growth could accelerate mainstream adoption. The balance between these strategies will determine not only which country leads, but also how stablecoins are integrated into the world economy.
