Meaning
The kanji 袋 (ふくろ / fukuro) fundamentally means a "bag," "sack," or "pouch." It refers to a flexible container, typically made of cloth, paper, plastic, or similar pliable materials, used for holding various items. Unlike a rigid box (箱), a 袋 conforms to the shape of its contents. This kanji is very common in daily Japanese life; you'll see it everywhere, from grocery shopping to traditional accessories.
Let's look at its etymology to understand why it means 'bag'. The kanji 袋 is a compound ideograph, combining two main components. On the left is the radical 衣 (い / いへん or ころもへん), which means "clothing" or "garment." This radical immediately signals that the kanji relates to fabrics, materials, or something made of cloth. The right component is 代 (だい / かわる), which often means "substitute," "generation," or "replace." In the context of 袋, 代 likely functions primarily as a phonetic component, providing the "tai" sound (as in the On'yomi タイ).
However, you could also interpret the combination as 'a cloth (衣) container that substitutes (代) for carrying things by hand.' Or, think of it as 'a receptacle that takes the place of something else.' This connection to flexible materials and holding contents makes the meaning of "bag" quite intuitive. The kanji 袋 has 11 strokes and is taught in the 6th grade in Japanese elementary schools, placing it at the N3 level for the JLPT exam.
Readings
On'yomi (音読み) — Chinese-derived readings
The On'yomi reading for 袋 is タイ (Tai). While this reading is officially listed for 袋, it is quite rare in everyday Japanese and in common compound words. Most frequently, when 袋 appears in compounds, it uses its native Japanese Kun'yomi reading. Therefore, beginners should primarily focus on the Kun'yomi reading, as it is much more common in practical usage. You might encounter タイ in very specific or archaic terms, but it's not a go-to reading for common vocabulary.
Kun'yomi (訓読み) — Native Japanese readings
The primary and by far most common Kun'yomi reading for 袋 is ふくろ (fukuro). This reading is used both when the kanji stands alone and in the vast majority of compound words. When 袋 is part of a compound, especially as the second kanji, its reading often undergoes a sound change phenomenon known as rendaku (連濁), where ふくろ changes to ぶくろ (bukuro).
- 袋 (fukuro) — bag, sack, pouch
This is the standalone reading of the kanji, referring to any general bag or sack. It's an essential everyday word.
- 紙袋 (kamibukuro) — paper bag
Here, 袋 changes to ぶくろ due to rendaku, combining with 紙 (paper) to mean a paper bag.
- 手袋 (tebukuro) — glove, mitt
Literally "hand bag," this word also demonstrates rendaku with 手 (hand) to mean a glove, a bag for your hand.
- ゴミ袋 (gomibukuro) — trash bag
Combining the loanword ゴミ (gomi, trash) with 袋 (which again becomes ぶくろ), this refers to a bag specifically for garbage.

Memory Tip
To remember the kanji 袋 (ふくろ), visualize its two main components. On the left is the radical 衣 (ころもへん), which means "clothing" or "garment." This immediately brings to mind something made of flexible material, like cloth. On the right is 代 (だい), which can mean "substitute" or "generation," but also acts as a phonetic component. Picture a person needing to carry something, so they grab a piece of "clothing" (衣) to "substitute" (代) for a basket, tying it up to make a simple "bag." The 衣 radical strongly links the kanji to fabric or flexible coverings. Meanwhile, 代 helps with the pronunciation hint (タイ) and the concept of something serving a function. Thus, a "clothing-made substitute" equals a "bag."
