Nintendo Japan has officially warned users not to use the Nintendo Switch or the upcoming Switch 2 in environments below 5 °C or above 35 °C. The alert comes in response to rising summer temperatures across Japan and other regions, where handheld gaming outdoors could trigger performance issues or even cause system shutdowns.

故障の原因となる可能性がありますので、5～35℃の場所でご使用ください。
最近は35℃を超える日が続いています。屋外で使用する際はご注意ください。
The statement emphasized that high temperatures may lead to console overheating, especially in handheld mode without proper ventilation. In recent weeks, users in Japan have already reported aggressive fan noise and random crashes, even while playing lightweight titles. The guidance also includes a rare mention of low-temperature dangers, where cold environments might cause condensation or battery problems.
This marks one of the first clear thermal usage limits from Nintendo, a move that seems increasingly necessary as climate conditions continue to intensify. It’s not just Japan—regions like Turkey, Southern Europe, and parts of the US routinely exceed 35 °C in summer months, making the warning globally relevant.
While the Switch 2 has not yet been officially released, this early advisory signals a proactive safety push for next-gen hardware. Players are encouraged to play indoors or in climate-controlled environments to preserve device lifespan and performance.
