Meaning
The N1 kanji 潟 (kata/kei) evokes images of serene lagoons, bustling inlets, and expansive tidal flats. Though its 15 strokes might seem daunting initially, understanding its components makes it far more accessible.
潟 refers to a specific geographical feature: a shallow body of water, often separated from the sea by a sandbar or reef, or a flat area of shoreline that is submerged at high tide and exposed at low tide. It perfectly captures images like a peaceful lagoon teeming with birds or a vast tidal flat abundant with marine life.
Examining its visual structure reveals that the familiar water radical 氵 (sanzui) on the left clearly indicates a connection to water. On the right, 泻 (often simplified as 瀉) serves primarily as the phonetic component, guiding its pronunciation. However, it also offers a subtle semantic hint. The character 瀉 itself can mean "to pour" or "to flow," suggesting water that spreads out or recedes. This aptly describes the nature of lagoons and tidal flats, where water ebbs and flows. Thus, 潟 combines "water" (氵) with a component implying "spreading out" or "flowing," resulting in the meaning of a shallow, often enclosed, body of water or a flat area influenced by tides.
This kanji has 15 strokes and is not assigned a specific school grade level. As part of the advanced N1 JLPT curriculum, it's expected knowledge for learners with a comprehensive understanding of Japanese.
Readings
This section explores the pronunciation of 潟. This kanji is notable because its native Japanese readings are much more common than its Chinese-derived readings, especially in prominent place names.
On'yomi (音読み) — Chinese-derived readings
The primary On'yomi for 潟 is ケイ (KEI).
ケイ (KEI): This reading is exceptionally rare in modern Japanese compounds. You'll seldom encounter it outside of specific academic contexts, historical texts, or highly specialized geographical terminology. In fact, it's so uncommon that many native speakers might not even recognize it as a reading for this kanji when seen alone.
While ケイ exists as a formal reading derived from its Chinese pronunciation, it has largely been superseded by the Kun'yomi in common usage. Finding everyday examples is impractical. If you do encounter it, it's likely in an obscure or ancient place name like 潟嶺 (Keirei), an old geographical term. For JLPT purposes, focus primarily on the Kun'yomi.
Kun'yomi (訓読み) — Native Japanese readings
The Kun'yomi of 潟 is かた (KATA), which is where this kanji is most frequently encountered in practical use.
かた (KATA): This is the reading you'll encounter most frequently. It's central to many geographical terms and, most famously, in the name of a major Japanese prefecture and its capital city. When 潟 appears on its own, it can refer directly to a lagoon or inlet, though it's more often found as part of a compound.
潟 (kata) — lagoon; inlet; mudflat. While less common than in compounds, it can function as a standalone noun.
あの 潟は渡り鳥の楽園だ。 — That lagoon is a paradise for migratory birds.
Due to rendaku (連濁), this reading also appears as がた (gata) when combined with other kanji, particularly in place names. This pronunciation shift is crucial for recognizing the kanji in many geographical contexts.
新潟 (Niigata) — Niigata (a prefecture and its capital city, literally "new lagoon"). This is perhaps the most famous example of the kanji 潟 in use.
干潟 (higata) — tidal flat; mudflat (literally "dry lagoon/flat," referring to land exposed at low tide).
砂潟 (sunagata) — sandy lagoon; sandy flat (a lagoon or tidal flat with sand).

Memory Tip
To help remember 潟, its components can be dissected. On the left, you'll see the familiar water radical, 氵 (sanzui), immediately signaling its connection to water. The right side, 泻 (or 寫 in its full form), conveys the idea of water 'spreading out' or 'flowing away.' Imagine water pouring from a tap, spreading thinly over a flat surface. Thus, 潟 combines 'water' (氵) with the concept of 'spreading out' (瀉), forming the image of a flat, shallow body of water. This could be a lagoon where water gently spreads out, or a tidal flat where water recedes from the land. This visual link of 'water spreading' effectively reinforces 潟 and its meaning.
