Japanese novel 'BUTTER' has achieved remarkable success in the English-speaking market. This cultural phenomenon has piqued international interest in Japanese literature, overcoming language barriers through quality translation. The reasons behind this success and its implications for future transnational literary endeavors will be explored in detail.

The success of 'BUTTER' resonates strongly within Japan as a symbol of national pride in its literary heritage and as inspiration for domestic authors to seek global recognition. Cultural storytelling, the spirit of "omotenashi" (Japanese hospitality), and the distinct storytelling style are considered contributing factors to its success.

In the US or EU, foreign literature successes are often regarded as ways to explore new cultures or diversify reading habits. However, they also illustrate the pervasiveness of the English language and hint at potential language dominance in the global literary market.
