why does anime have Wide Eyes?

There are many theories and reason why anime features large eyes, the most commonly accepted one is as follows.

Osamu Tezuka, known as "the father of manga", started drawing hoạt hình with large eyes in his earliest works because he got much of his inspiration from Walt Disney and other Western animations (Bambi, Betty Boop, Snow White, all have large eyes). Due to the popularity of his works, the style has kept all these years.

Other reasons include:
Large eyes have often been a characteristic of beauty

Large eyes make it easy to convey many different types of emotion

The Japanese phrase of "The eyes are the window to the soul"
