満腹な

This is the most common and natural everyday expression for 'full stomach.'

Means 'satisfactory' or 'content,' not physically full.

Means 'full (container)' or 'one cup/glass' unless part of the phrase お腹がいっぱい.

This is a common, more casual way to express 'full stomach.' Learners might get confused about when to use the adjective 満腹な versus this phrase.

満腹な (manpuku na) is a な-adjective, often used in slightly more formal contexts or for a stronger emphasis on being completely satiated. お腹がいっぱい is a more natural, everyday expression.

もうお腹がいっぱいだから、デザートはいらない。 (My stomach is full already, so I don't need dessert.)

Both 満腹 (manpuku) and 満足 (manzoku) use the character 満 (man), which means 'full.' This can lead to confusion about their specific meanings.

満足な (manzoku na) means 'satisfactory' or 'content.' While you might feel satisfied after a full meal, it's about general contentment, not specifically a full stomach.

彼の提案は私にとって満足なものだった。 (His proposal was satisfactory to me.)

一杯 (ippai) can mean 'full' in a general sense (e.g., 'the glass is full') and is also part of the phrase お腹がいっぱい. Learners might incorrectly use 一杯 on its own to mean 'full stomach.'

一杯 (ippai) on its own usually refers to a container being full, or 'a cup/glass of something.' When used for a full stomach, it's typically in the phrase お腹がいっぱい.

コップに水を一杯入れてください。 (Please fill the glass with water.)

Another word using 満 (man), meaning 'full.' The presence of the same character can be misleading.

満員 (man'in) specifically means 'full (of people)' or 'no vacancies.' It's used for places like trains, theaters, or hotels, not stomachs.

電車は満員だった。 (The train was full of people.)

Yet another word with 満 (man), but with a very specific meaning that can be confused due to the shared character.

満開 (mankai) means 'in full bloom,' typically used for flowers, especially cherry blossoms. It has no relation to feeling full after eating.

桜は今、満開だ。 (The cherry blossoms are in full bloom now.)
