The rising cost of dynamic random access memory (DRAM) could potentially trigger an increase in video game console prices in Japan. With DRAM being a critical component in these devices, manufacturers might no longer be able to absorb the additional costs. Therefore, a bump in retail prices might be unavoidable, causing concerns among gamers and industry stakeholders.

Japan being home to several gaming console giants like Sony and Nintendo, any change in production costs has significant ramifications in the local market. Residents display a high degree of brand loyalty. Thus, a steep price increase could stir dissatisfaction. Moreover, the issue highlights the country's ongoing struggle with tech industry supply chain challenges.

Similar to Japan, the US and EU are no strangers to such tech industry challenges. However, market responses can vary significantly due to the higher competition level in these regions, different consumer behaviors, and the companies' respective marketing strategies.
