Meaning of 最も多い in this sentence > **** > Every year in Japan ??? more than 36,000 people run. I can't understand at all what does in this sentence. Literally it means 'most numerous' right? I can't understand it's meaning in this context or even how it fits in grammatically. Presumably it modifies since that's the only available noun. But thereafter, I'm lost.

In this context, the following could safely be inferred.

{}{}{}{}{}

What is is the number of participants in the marathon.

> "Every year, over 36,000 people, which is the largest scale in Japan, run/participate."

A literal translation would be close to impossible, which is why I used "the largest scale". A slightly more literal TL would be:

> "Every year, over 36,000 people, which is the most in Japan, run/participate (in this marathon)."
