Atami offers a large variety of different flowerpots, to each grower’s preference. Flowerpots often do not contain enough holes in the bottom (drainage holes), which makes drainage difficult. With poor drainage the substrate in the pot will quickly turn into a quagmire which results in lack of oxygen, so the root system becomes damaged and will start to rot.
To prevent such tragedies the flowerpots of Atami have been designed in such a manner that excess water can always drain away. This makes growing a lot more pleasant.
