📝 Usage Notes
all at once
📖 How to use it
Describes doing or happening of multiple things at the same single time.
Attaches to
Attaches to a noun phrase: [noun] + 一度に. It is also used as an adverb before a verb or adjective, often with a number or quantity expression.
一度に means 'all at once' or 'in one go'. It emphasizes that several actions or events happen simultaneously or are done in a single instance, rather than one by one. For example, you might use it when you eat many pills at once, or when too many people enter a room at the same time. It often carries a nuance of 'too much at once' or 'all together', so it is used when the amount or number is notable.
This pattern is common in everyday speech and writing. It is not limited to formal contexts, but it is neutral and can be used in polite conversation as well. Note that 一度に is not the same as 'once' (一回) – it means 'in one go', not 'one time'.

Not 一度は (ichido wa)
一度に means 'all at once', focusing on simultaneity, while 一度は means 'at least once', focusing on frequency. For example, 一度に食べる means 'eat all at once', but 一度は食べる means 'eat at least once'.
