This is Tamba Tachikui ware, a traditional craft from Japan. It has a calm, brown color. The size of the tokkuri (sake bottle) is: base diameter 5cm, spout 3-4cm, height 17cm. There are two ochoko (sake cups) with a diameter of 5.5cm and a height of 4cm. These items have been stored at home for a long time, so the box has scratches and dirt.
