Questions & Answers about kuuraabokkusu wa omoi.
Because when は is used as the topic particle, it is pronounced wa, not ha.
So in this sentence:
- クーラーボックス = cooler box
- は = topic marker, pronounced wa
- 重い = heavy
This is one of the first pronunciation exceptions learners meet in Japanese. The spelling stays は, but the pronunciation becomes wa when it is a particle.
は marks the topic of the sentence.
So クーラーボックスは重い means something like:
- As for the cooler box, it is heavy.
In natural English, we usually just say The cooler box is heavy, but the Japanese structure is more like introducing a topic and then saying something about it.
A useful way to think of it:
- クーラーボックス = the thing we are talking about
- 重い = the comment about that thing
