Means 'to count on' or 'to expect something from someone', often with a nuance of expecting a specific outcome or favor. Can sound slightly more calculating.

Can also be used for things, especially when expecting a certain result or benefit.
Expressing that you are counting on a future event or situation occurring.
A simple way to say you are counting on something happening, often with the nuance of 'I expect that...'. Use with a clause ending in plain form.

Expresses a strong expectation based on reason or logic. 'It should be that...' or 'I expect that...'.

Means 'to expect' or 'to hope for'. More formal and less casual than other options. Often used in written or formal contexts.

Specifically expressing reliance on a person to perform an action.
A natural pattern meaning 'to have someone do something for you', implying you are counting on them to do it. The person is marked by に, and the action is in て-form.

A more explicit way to say 'I'm counting on someone to do something for me'. くれる indicates the action is a favor.

The English phrase 'count on' cannot be directly translated into Japanese using the verb 数える (to count). Using 数える in this context will result in nonsense. Always use expressions of reliance or expectation.
頼りにする is the most common and neutral for relying on a person. 頼る can imply a heavier dependence, sometimes negative. 当てにする often carries a nuance of expecting a specific benefit or outcome, and can sound presumptuous if overused.
I count on him (as a reliable person).
You shouldn't always count on him (depend too much).

Natural Japanese often uses 任せる (entrust) instead of a direct 'count on' phrase.
