A new game show titled "Meruru" has taken Japan by storm, demonstrating a novel way for actors to remember their lines instantly. Contestants on the nationwide broadcast are given a challenging script they've never seen before, and they have to perform it correctly after a very brief glance. The audience excitement grows as the difficulty level of the lines increases, creating a thrilling element of suspense and amazement.

Japanese society places a high value on memory skills, given its language complexities and script variations. "Meruru" becomes a topic of interest as it links entertainment with this societal expectation. Its popularity also reflects Japan's love for game shows and the admiration for those who can master the skill of quick memorization.

Similar to Japan, memory skills are praised in the US and EU, but not to the same extent, primarily because English has an easier script to memorize. Furthermore, though there are memory-focused game shows in these regions, the specific theme of quick line memorization in a performance context is unique to Japan's "Meruru".
