Questions & Answers about watashi wa kyouto e iku node, oufuku no kippu o kaimashita.
は marks 私 as the topic of the sentence. It tells you that the sentence is about me.
So 私は means something like:
- As for me, ...
- I ...
In natural English, we usually just translate it as I, but the nuance is slightly different. Japanese is setting up 私 as the topic, not just marking it as the grammatical subject.
It could definitely be omitted if the speaker is already understood from context.
Japanese often leaves out subjects and topics when they are obvious. So this could also be:
- 京都へ行くので、往復の切符を買いました。
That would still naturally mean I bought a round-trip ticket because I’m going to Kyoto, assuming the speaker is talking about themself.
Using 私 makes it clearer or slightly more explicit.
