Bonsai in four cards
Four words take you from the art itself to its daily care: the tree in its tray, the pot, the pruning and the watering that every bonsai lover talks about.

| Japanese | Romaji | Meaning |
|---|---|---|
| 盆栽 | bonsai | a tree grown in a tray |
| 鉢 | hachi | a pot for plants |
| 剪定 | sentei | pruning |
| 水やり | mizuyari | watering |
Hachi is the general word for a plant pot; for bonsai you will also hear bonsai bachi, a bonsai pot, where hachi changes to bachi in the compound. Mizuyari literally means giving water and is the everyday word for watering any plant.
The two kanji: 盆 and 栽
盆 (bon, 9 strokes) means a tray or shallow basin, and its lower part is 皿, a dish. It is the same kanji as in Obon (お盆), the summer festival of the ancestors, and in obon meaning a serving tray; context tells you which is meant. 栽 (sai, 10 strokes) means to plant or cultivate. On its own it is rare, but you see it in saibai (栽培), cultivation, and in a few gardening words.
So bonsai is, quite literally, tray planting. The word refers both to the art and to an individual tree: you can say bonsai ga shumi desu, my hobby is bonsai, or kono bonsai wa kirei desu ne, this bonsai is beautiful.
| Japanese | Romaji | Meaning |

| お盆 | obon | a serving tray; also the Obon festival |
| 栽培 | saibai | cultivation, growing plants |

Where bonsai came from
The art of growing small trees and landscapes in containers developed in China, where it is known as penjing. It reached Japan many centuries ago, and paintings and scrolls from the Kamakura period already show potted trees. Over time, Japanese growers developed their own styles, and in the Edo period bonsai became popular among samurai, merchants and townspeople alike. Exact dates and routes are discussed by historians, so treat these as broad strokes.
In the early twentieth century, a group of bonsai growers moved from Tokyo to Ōmiya, now part of Saitama City, and founded what is known as the Ōmiya Bonsai Village. It still has several bonsai gardens, and a public bonsai art museum stands nearby. From Japan, the word bonsai spread around the world, and today there are enthusiasts and clubs in many countries.

Common styles, and what makes a good bonsai
Bonsai are classified by the shape of the trunk and branches, the jukei (樹形). These are the styles you are most likely to see at a show. Enthusiasts admire a tree that looks old and natural, with a strong base, a trunk that tapers upwards, balanced branches and a pot that suits the tree. Many connect bonsai with ideas of patience and quiet beauty, but people describe its appeal in many different ways.

| 懸崖 | kengai | cascade style |
| 寄せ植え | yoseue | group planting |

| Formal upright | Chokkan | A straight trunk rising to a point |
| Informal upright | Moyōgi | A trunk that curves gently as it rises |
| Slanting | Shakan | A trunk that leans to one side, as if in the wind |
| Cascade | Kengai | Branches that fall below the pot, like a tree on a cliff |

Mini dialogue: choosing a first tree
Many nurseries sell small, inexpensive trees for beginners, and owners are usually happy to give advice. Here is a typical exchange.
| Japanese | Romaji | Meaning |
|---|---|---|
| 盆栽を始めてみたいんですが。 | Bonsai o hajimete mitai n desu ga. | You: I'd like to try starting bonsai. |
| 初めてなら、この真柏がおすすめです。 | Hajimete nara, kono shinpaku ga osusume desu. | Owner: For a first tree, I'd recommend this juniper. |
| 水やりはどのぐらいしますか。 | Mizuyari wa dono gurai shimasu ka. | You: How often do I water it? |

Many traditional bonsai trees, such as pines and junipers, are outdoor plants that need sun, wind and the change of seasons. If you want a tree for indoors, ask the nursery specifically: heya de sodateraremasu ka, can I grow it in a room?

Common learner mistakes
- Saying banzai for bonsai. Banzai (万歳) is a cheer; bonsai is the tree art.
- Calling any small potted plant a bonsai. In Japanese, bonsai implies a tree shaped with care, not just a small houseplant.
- Touching the trees at a show. Look closely, but keep your hands back.
- Writing 盆才 or 盆裁. The correct kanji is 栽, with 木 at the bottom left.
