It is also used in Japanese to refer  to someone that has multiple skills.

The original 'NITOURYU' was Miyamoto Musashi,  a Japanese samurai from the Edo period, about 400 years ago.

He was an expert swordsman, he was also  an expert at using two swords at the same time.  

He won over 60 duels and  wrote The Book of Five Rings. 

The legendary baseball player Babe Ruth can  also be considered 'NITOURYU' as he started  his career as a pitcher for the Boston Red Sox.

But since his batting was so good he was moved  to the starting lineup as a regular player so  that he could be in the batting order every day.  

He was traded to the New York Yankees and became  the legendary player that we all know today.

And this takes us to the Japanese baseball  phenomenon Shohei Ohtani who almost  100 years after Babe Ruth is playing as both a  starting pitcher and batter for the Angels. 

Not only is he 'NITOURYU'  but he is excelling at it  being the first player voted to the  All-Star game as both a batter and a pitcher.

He has surpassed Hideki Matsui as the Japanese  player to hit the most home runs in a season.  

And he's only at the halfway mark so far. 

He is one of the few American League  players to be leading in home runs and  stolen bases before the All-Star break  

and it looks like he'll be in the home run derby  at the All-Star game.

So it's just an incredible  achievement and a phenomenon like we haven't  seen since Babe Ruth and maybe Miyamoto Musashi.  

Japanese media is always referring to Shohei Ohtani  as 'NITOURYU' and in doing so they're showing that he's a skillful player in baseball,

more than just  a pitcher or a batter, he's also stealing bases.

But in doing so they're also invoking the spirit  of the Japanese samurai Miyamoto Musashi and in  that sense they're equating him to a legend. 

So he's very popular in Japan and very popular  amongst baseball fans and sporting fans   in the world. It is a very exciting time for sports.
