1:47 PM PT -- Shohei Ohtani just revealed more about his wife during a meeting with media members out at spring training on Thursday ... saying the two knew each other around three or four years before tying the knot.

The baseball star also said she had "nothing to do" with his decision to leave the Angels and join the Dodgers this offseason.

Shohei Ohtani is officially off the dating market ... the MLB superstar revealed late Wednesday night he's now married!!!

The Dodgers' designated hitter said in a post on his Instagram page his new spouse is "someone from my Native country of Japan who is very special to me" ... although he did not reveal the person's name.

"I am excited for what is come," he wrote ... before adding, "thank you for your support."

Ohtani included a picture of his adorable dog, Decoy, on the announcement as well.

Of course, it's now the second time in the last three months the 29-year-old has told the world of a life-changing event on IG ... back in December, he shared he was moving on from the Angels to the Dodgers for the foreseeable future.

That announcement got over two million "likes" on the social media app ... and so far, it's appeared to be a great decision for the two-way player.

Ohtani homered in his first spring training game with the team earlier this week, and he looks poised for a huge 2024 -- even if he won't pitch this year while recovering from elbow surgery.

Only about three more weeks until the at-bats actually count for L.A. ... get that popcorn ready!
