Same Kanji, Different Readings and Meanings: A Guide to Commonly Confusing Kanji

In the process of learning Japanese, learners often encounter kanji that appear familiar but are read differently, or seem to carry an entirely different meaning.

In Japanese, a single kanji—or a combination of kanji—can have multiple readings and meanings. A change in reading alone may shift the reference from a concrete object to an abstract evaluation, or from a general concept to a specific description of a state or condition.

In this article, we focus on four commonly confusing words—銀杏, 上手, 人気, and 流石—which learners often struggle with despite encountering them frequently in daily life.
We will examine their different readings and meanings, the contexts in which each is used, and how native Japanese speakers determine the appropriate reading.

First, it is important to understand several fundamental characteristics of Japanese kanji:

・音読み(On-yomi): readings that developed from the Chinese pronunciation when kanji were     introduced to Japan

・訓読み(Kun-yomi): readings based on native Japanese words to which kanji were later assigned

・熟字訓(Jukujikun): readings in which multiple kanji are combined and given a unique, Japanese-specific pronunciation

Because of these characteristics, a single kanji—or a kanji compound—can carry multiple readings and meanings, depending on how and where it is used.

Here are three common reasons why kanji readings change:

1. The referent changes — for example, whether the kanji refers to the object itself (such as a tree) or to its product (such as its fruit).

2. The speaker’s perspective changes — whether the expression reflects an evaluation, a position, or a role.

3. The context changes — whether the sentence is about reputation, assessment, or the existence of a person or thing.

Native Japanese speakers interpret these elements intuitively based on context, and select the appropriate reading accordingly.

Let’s take a look at some examples.

Ginkgo trees are well known for their golden leaves that color entire cities in fall. When learners encounter the kanji 銀杏, they may wonder whether it should be read as ichō or ginnan. In fact, the reading changes depending on whether the word refers to the tree itself or to its nut.

Example 1:
校庭に銀杏（ichō）の木が植えてあります。
–A ginkgo tree is planted in the schoolyard.

Example 2:
茶碗蒸しに銀杏（ginnan）が入っています。
–Ginkgo nuts are included in the chawanmushi.

Although both forms use the same kanji, 銀杏 is read as ichō when it refers to the tree itself, whereas it is read as ginnan when it denotes the edible seed. Because the semantic distinction between these two usages is explicit, the corresponding readings are strictly fixed.

The key to this distinction lies in what the speaker is perceiving.
When looking up at the sky and thinking “beautiful,” the reference is to ichō, the tree itself.
By contrast, when looking at a dish and finding it appetizing—or noticing its distinctive aroma—the reference shifts to ginnan, the edible seed.

The meaning of 上手 varies significantly depending on its reading and the context in which it is used.

Example 1:
彼は日本語がとても上手（jōzu）です。
–He is very good at Japanese.

Example 2:
その俳優は上手（kamite）から登場しました。
–The actor entered from stage right.

Example 3:
彼のほうが私より一枚上手（uwate）だ。
–He is one step ahead of me.

Jōzu is frequently used in everyday language to express an evaluation of someone’s skills or abilities.

By contrast, kamite is a relatively specialized term, used in specific contexts such as theater, performing arts, traditional arts, and sports, where it indicates a positional or spatial reference, particularly on a stage. Its opposite term is shimote.

Uwate refers to a situation in which one person is a step ahead of another in terms of ability, strategy, or interpersonal maneuvering.

For this reason, the statement “彼は上手だ” on its own is inherently ambiguous. Without additional context, it is unclear whether the speaker is evaluating his ability (jōzu) or describing his advantage over someone else (uwate).

In practice, the reading is determined by the direction of the topic and the speaker’s perspective. When the discussion focuses on skill or ability, the reading jōzu is used. References to stage or physical space lead to the reading kamite, while discussions involving interpersonal relationships or strategic interactions result in the reading uwate.

Many learners become confused after first learning 人気 (ninki) as meaning “popular” at the beginner level and later encountering its different reading, hitoke.

Example 1:
あのアニメは若者に人気（ninki）がある。
–That anime is popular among young people.

Example 2:
夜の公園は人気（hitoke）がなくて怖い。
–The park at night is scary because there are no people around.

Ninki expresses public evaluation and describes a state of being liked or well regarded, while hitoke refers to the presence or sense of people in a place. The expression hitoke ga nai is often learned and remembered as a fixed expression).

If the phrase “人気のない店” is read as ninki no nai mise, it conveys the meaning of an unpopular or unappealing shop. However, when read as hitoke no nai mise, it takes on a very different nuance, describing a quiet, secluded shop with no customers present, much like a hidden retreat. With a single change in reading, the impression of the shop shifts completely—whether it is perceived as lacking vitality or as being enveloped in silence can change by 180 degrees.

The final example demonstrates a particularly significant difference, both in meaning and in frequency of use.

Example:
流石（sasuga）プロですね。
–As expected of a professional.

The word sasuga is used to express admiration or acknowledgment that someone’s performance meets (or exceeds) expectations. Sasuga is widely used in both everyday conversation and written texts. By contrast, ryūseki represents Sino-Japanese, literary reading and is rarely used in modern Japanese.

Another challenge in learning Japanese lies in the fact that, although certain readings are listed in dictionaries, some are not actively used in contemporary language.

Native speakers unconsciously integrate the following elements:
・what is being referred to (object, person, or evaluation)
・the situation (meal, stage, nighttime street, etc.)
・the surrounding words (kowai, jōzu, tōjō suru, etc.)

Japanese includes many cases in which the same kanji has different readings and meanings, which can feel overwhelming for learners. However, such words tend to share certain characteristics:
・clear distinctions in meaning
・relatively fixed situations in which each reading is used

Therefore, it is important to learn these words while being mindful of the situations in which they are used and what they represent, together with example sentences, rather than simply memorizing multiple readings.
By understanding the different aspects of each word written with the same kanji, both reading comprehension and expressive ability can develop to a higher level.

We encourage you to take a moment to consider in which meaning a kanji is used within familiar sentences or everyday conversations.
