By using a verb in the plain form + つもり, you can express your intention or plan to do something.
For example, if you are going to Japan in the spring, you could say 春に日本へ行きます. This explains what you are going to do, but if you want to express your definite intention to do it, or if you are planning on it but not certain it will happen yet, you can instead say 春に日本へ行くつもりです.
See the below table for some example sentences using this pattern.
