Incidentally, bonsai with trunks and branches growing downwards below the rim of the pot are called Kengai style bonsai and those with the trunks and branches at about the level of the rim of the pot are called Han Kengai (semi-cascade) style bonsai.
ちなみに、幹や枝が鉢の上縁よりも下に垂れ下がっているものを懸崖、鉢の上縁ぐらいのものを半懸崖、と呼ぶ。
