Sumo wrestling

I went to watch Sumo wrestling in a Shinto shrine. It was free of charge. There were many foreign tourists.

It was not usual Sumo match* but** was*** offered to the Shinto deity. Sumo is a Japanese traditional sport but origin of it was one of Shinto rituals.

These days, the grand champions are foreigners from Mongol or Europe but we enjoy Sumo match**** anyway.

* It sounds like this is a singular match that you're talking about. If you put the word in the singular form it would need "a/an" in front of it. If you are talking about many sumo matches you get rid of "a/an" and add an "s" on match.

** "But" is used for contridiction, a sentrncd that you would consider to be the opposite of the first part follows after "but." "The weather was good in the morning, but it rained in the afternoon." "At first he seemed like a mean old man, but it turned out he was really nice."

*** The subject is missing before was. You talk about something being offered, likely the sumo match, but you didn't say what it was.

*** Same thing as before with "a match" vs "sumo matches"
