Learning Goal

By the end of this lesson, you will be able to read, write, and understand 6 N3-level kanji related to nature and the environment. You will learn their meanings, common readings, and how to use them in everyday words and sentences.

Concept

Nature and environment kanji often appear in news, weather reports, and daily conversation. These characters describe elements like forests, oceans, mountains, and weather. Learning them together helps you build a mental "nature vocabulary" set. Each kanji has a core image (like a tree or water) that makes it easier to remember.

Step-by-Step Breakdown

1. 森 (mori) – Forest

Meaning: Forest, woods, grove
On'yomi (Chinese reading): シン (shin)
Kun'yomi (Japanese reading): もり (mori)
Stroke count: 12
Writing tip: Three 木 (tree) characters stacked. The top tree is slightly smaller. Think: "many trees together = forest."
Memory tip: Picture three trees standing close together. The more trees, the denser the forest.

Example words:

森林 (shinrin) – forest, woods
森の中 (mori no naka) – inside the forest

2. 海 (umi) – Sea / Ocean

Meaning: Sea, ocean
On'yomi: カイ (kai)
Kun'yomi: うみ (umi)
Stroke count: 9
Writing tip: Left radical is 氵 (water). Right side is 毎 (every). Think: "water everywhere = sea."
Memory tip: The right side 毎 looks like waves with a person. Imagine the sea covering everything.

Example words:

海 (umi) – sea
海外 (kaigai) – overseas (literally "outside the sea")

3. 山 (yama) – Mountain

Meaning: Mountain
On'yomi: サン (san)
Kun'yomi: やま (yama)
Stroke count: 3
Writing tip: Three strokes. The middle line is tallest. Draw a central peak with two smaller sides.
Memory tip: The character looks like a mountain peak from the side. Simple and iconic.

Example words:

山 (yama) – mountain
火山 (kazan) – volcano (fire + mountain)

4. 川 (kawa) – River

Meaning: River, stream
On'yomi: セン (sen)
Kun'yomi: かわ (kawa)
Stroke count: 3
Writing tip: Three strokes. The left stroke curves slightly, the middle is straight, the right curves opposite. Think of flowing water.
Memory tip: The three strokes represent the flow of a river: left bank, center current, right bank.

Example words:

川 (kawa) – river
小川 (ogawa) – stream, brook (small river)

5. 空 (sora) – Sky / Empty

Meaning: Sky; also emptiness, air
On'yomi: クウ (kuu)
Kun'yomi: そら (sora), あ (ku) (as in 空く "to be empty")
Stroke count: 8
Writing tip: Top is 穴 (cave/hole) radical. Bottom is 工 (work). Imagine a hole in the sky where work happens.
Memory tip: The top part looks like a roof (sky above). The bottom 工 suggests "construction" – the sky is always being built with clouds.

Example words:

空 (sora) – sky
空気 (kuuki) – air (sky + spirit/gas)

6. 天 (ten) – Heaven / Sky / Weather

Meaning: Heaven, sky, weather, nature
On'yomi: テン (ten)
Kun'yomi: あめ (ame), あま (ama)
Stroke count: 4
Writing tip: One horizontal line at top (the heavens), then 大 (big) below. Think: "the big thing above."
Memory tip: The top line is the horizon. Below it is a person (大) reaching up to heaven.

Example words:

天気 (tenki) – weather (heaven + spirit)
天国 (tengoku) – heaven, paradise

Mini Examples

Kanji	Word	Romaji	English
森	森林	shinrin	forest
海	海辺	umibe	seaside
山	山道	yamamichi	mountain path
川	川岸	kawagishi	riverbank
空	青空	aozora	blue sky
天	天気予報	tenki yohou	weather forecast

Common Mistake

Mistake: Confusing 天 (ten) with 空 (sora).

Why it happens: Both can mean "sky" in some contexts.

How to avoid:

天 (ten) is more abstract: heaven, weather, the sky as a concept.
空 (sora) is the physical sky you see above you.

Example of correct use:

今日の天気はいいです。 (Kyou no tenki wa ii desu.) – Today's weather is good. (Use 天, not 空)
空が青いです。 (Sora ga aoi desu.) – The sky is blue. (Use 空, not 天)

Summary and Next Step
