俗语说“民以食为天”不同地区的人民在历史演变中会形成自己独有的地区文化，饮食文化作为民族文化的重要体现不仅反映着人们对生活的追求，更体现出该民族的精神内核。日式便当作为日本饮食文化中的一道风景，不仅在日常生活中能够满足人们对食物需求，更可以体现日本人的性格和习惯，并且在随着社会经济的发展中逐渐形成独树一帜的日本便当文化。

As the saying goes, "the people take food as the sky", people in different regions will form their own unique regional culture in the historical evolution, and food culture, as an important embodiment of national culture, not only reflects people's pursuit of life, but also reflects the spiritual core of the nation. As a scenery in Japan's food culture, Japanese bento not only meets people's food needs in daily life, but also reflects the character and habits of Japanese people, and gradually forms a unique Japanese bento culture with the development of social economy.
