Bonsai Meaning: What 盆栽 Means and How to Talk About It

Bonsai (盆栽) means a tree planted in a tray: 盆 (bon) is a tray or shallow container and 栽 (sai) means planting. In Japanese it refers to the art of growing a real tree in a small pot and shaping it over years so it looks like a large, old tree in nature.

Bonsai Meaning: What 盆栽 Means and How to Talk About It

Most English speakers know the word bonsai, but fewer know what the two kanji say, or that the art is less about small trees than about suggesting a whole landscape in a pot. A bonsai is not a special dwarf species: it is an ordinary tree, often a pine, juniper, maple or flowering plum, kept small by pruning, wiring and careful repotting. This guide explains the meaning of each kanji and how the word is used, where the art came from, with honest hedges, and what makes a good bonsai in the eyes of enthusiasts. It also gives you the vocabulary of styles and care, phrases for a bonsai exhibition or a nursery, and a short dialogue with a bonsai grower. Along the way it warns about the classic mix-up between bonsai and banzai.

盆 (bon) is a tray and 栽 (sai) is planting: a tree planted in a tray

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.

Four picture cards: a small tree growing in a tray, a shallow ceramic pot, scissors pruning a branch, and a watering can over a tree.
The tree, the pot, the pruning and the watering: the core words of bonsai.

鉢hachia pot for plants

水やりmizuyariwatering

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.

JapaneseRomajiMeaning
お盆obona serving tray; also the Obon festival
栽培saibaicultivation, growing plants
盆栽が趣味です。Bonsai ga shumi desu.My hobby is bonsai.
この盆栽はきれいですね。Kono bonsai wa kirei desu ne.This bonsai is beautiful.

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.

JapaneseRomajiMeaning
盆栽は中国から伝わりました。Bonsai wa Chūgoku kara tsutawarimashita.Bonsai came over from China.
大宮盆栽村に行ってみたいです。Ōmiya bonsai mura ni itte mitai desu.I'd like to visit the Ōmiya Bonsai Village.
海外でも人気があります。Kaigai de mo ninki ga arimasu.It's popular abroad too.

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.

Popular bonsai trees include matsu (pine), momiji (Japanese maple), ume (Japanese plum), satsuki (a kind of azalea) and shinpaku (a type of juniper). Bonsai grown for flowers are called hanamono and those grown for fruit mimono.

At a bonsai show or nursery

Bonsai exhibitions and nurseries are friendly places, and owners usually enjoy talking about their trees. Look from the front, the shōmen, which the grower has chosen as the best view. Do not touch the trees, and ask before taking photos at private gardens.

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.

JapaneseRomajiMeaning
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?
土が乾いたら、たっぷりあげてください。Tsuchi ga kawaitara, tappuri agete kudasai.Owner: When the soil is dry, give it plenty.
部屋の中に置いてもいいですか。Heya no naka ni oite mo ii desu ka.You: Can I keep it indoors?
外の方が元気に育ちますよ。Soto no hō ga genki ni sodachimasu yo.Owner: It will grow better outside.

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.
Key points

A practical way to improve

Practise talking about a tree as if you were standing in front of one at a show. First, praise it: rippa na bonsai desu ne, and add a detail, miki ga kakkoii desu ne. Second, ask the owner two questions: jurei wa nannen gurai desu ka and teire wa taihen desu ka. Third, describe your own plant at home in two sentences, using mainichi mizuyari o shite imasu. Watch the pronunciation of bonsai: two clear syllables, bon and sai, not banzai. Then ask Mocchi, Unihongo's study assistant, to make flashcards of the bonsai words, and review them until you can name each style from its shape.

FAQ

Frequently asked questions

What does bonsai mean literally?

Bonsai (盆栽) is made of two kanji. 盆 (bon) means a tray or shallow container, and 栽 (sai) means planting, as in saibai, cultivation. Together they mean something like tray planting: a tree grown in a shallow container.

Is bonsai Japanese or Chinese?

Both, in a sense. The practice of growing miniature trees and landscapes in containers developed in China, where it is called penjing, and came to Japan many centuries ago. Japan developed its own styles and aesthetics, and the Japanese word bonsai is the one the world now uses.

Is a bonsai a special kind of tree?

No. A bonsai is an ordinary tree or shrub, such as a pine, juniper, maple, azalea or plum, grown in a pot and kept small through pruning, wiring and repotting. With care, many bonsai can live for decades, and some famous trees are said to be centuries old.

What is the difference between bonsai and banzai?

Bonsai (盆栽) is the potted-tree art. Banzai (万歳) is a cheer meaning hooray or long live, shouted with both arms raised at celebrations. The words sound similar to English ears, so pronounce bonsai with a clear o: bon-sai.
