How is the 'hirachawan' mentioned in the description shaped differently from a regular rice bowl?

'Hirachawan (平茶碗)' literally refers to a bowl or cup made flat, just as the Chinese characters indicate. HAKUSAN's hirachawan also has a wider and flatter shape than a typical bowl-shaped vessel^[1].

This characteristic is also evident in the actual dimensions. HAKUSAN's Bloom series rice bowl has a concave size with a diameter of 11cm and a height of 5.5cm^[2]. On the other hand, ST-17 (ST-seventeen), selected in the hirachawan options, has the same height of 5.5cm, while its diameter is 15cm^[3][4].

While a concave and deep regular rice bowl is shaped to gather rice together, the hirachawan, with its wide opening and gentle bottom, is suitable for spreading out and serving not only rice, but also rice bowl dishes, salads, or side dishes with a small amount of broth.
