Meaning
The kanji 璃 (RI) primarily conveys the meaning of glass, lapis lazuli, and other similar transparent, lustrous, and often precious materials. It evokes a sense of clarity, beauty, and sometimes fragility. While often associated with man-made glass, its historical roots connect it deeply to natural gemstones. Lapis lazuli, a deep blue metamorphic rock, has been prized since antiquity for its intense color. This dual association with both manufactured glass and natural gems underscores its essence: a beautiful, often translucent substance.
璃 is a semantic-phonetic compound. Its left-hand radical, 玉 (tama or gyoku), meaning "jewel" or "jade," clearly indicates that the kanji refers to precious, gemstone-like materials. The right-hand component, 离 (ri), serves primarily as the phonetic element, giving the kanji its characteristic 'RI' reading. Interestingly, 离 can also subtly suggest separation or clarity. This aligns with glass's property of separating spaces while allowing vision through. Therefore, the visual components aptly convey its meaning: a clear, bright, jewel-like substance.
With 15 strokes, 璃 is designated as an N1 level kanji in the Japanese Language Proficiency Test, signifying its advanced usage. You won't find it in the standard elementary school kanji curriculum.
Readings
On'yomi (音読み) — Chinese-derived readings
The kanji 璃 almost exclusively uses its On'yomi reading. This pattern is typical for kanji representing specific materials or technical terms, especially those with strong Chinese origins or used predominantly in compound words rather than as standalone verbs or adjectives.
- リ (RI): This is the sole On'yomi reading for 璃 and is used in nearly all its common compounds. It frequently appears in words referring to glass, lapis lazuli, and similar translucent or glazed materials. It's often paired with other kanji to form specific terms for types of glass, colors, or objects made from these materials. For instance, in terms like 玻璃 (glass) or 瑠璃 (lapis lazuli), the 'RI' sound is consistently present.
Here are some common examples:
- 玻璃 (hari) — Glass. This is the most direct and common compound for the material itself.
- 瑠璃 (ruri) — Lapis lazuli; a deep blue gem or something of that color.
- 玻璃色 (hari-iro) — Glass color, often referring to clear or translucent hues.
Kun'yomi (訓読み) — Native Japanese readings
The kanji 璃 does not have any common Kun'yomi readings. This means it is not used as a standalone verb, adjective, or common noun in its native Japanese form. It almost always appears as part of a compound word, relying on its On'yomi to convey its meaning.

Memory Tip
To remember 璃, focus on its two main components. On the left, 玉 (tama or gyoku) is the radical for "jewel" or "jade." This immediately signals its connection to precious, beautiful, and often translucent or shiny materials, much like gemstones. The right side, 离 (ri), primarily functions as the phonetic component, giving the kanji its 'RI' reading. Picture a story: a dazzling "jewel" (玉) is so clear that light seems to "separate" (离) as it passes through, much like glass or a crystal prism. This vivid image of a clear, bright, jewel-like substance will help you cement its meaning of 'glass' or 'lapis lazuli' and its pronunciation.
