Because wen he got defeated in the Sinnoh League the guy that defeated him told him that he should travel to the Isshu Region,so he took a ferry trip to Isshu!
Yes, Ash goes to the Isshu region in the episode To the Isshu Region! Zekrom's Shadow!. Although Brock doesn't go with him, Ash will travel with people called Iris and Dento.
The Isshu Region.
The new region probably is called isshu.
Ash will go to the Isshu region. He takes pikachu along and will travel with Iris and Dento.
She was invited to a group of fashions(I HAVE NO IDEA WHAT IT WAS CALLED.) so she went there. I believe.
No...
He doesnt pick a starter in Isshu he actually catches all of them
dawn will not be with ash and the same goes with brock
I think the Isshu region is the same as Unova. And, no you can not trade pokemon from Unova/isshu to any other region because the older games have no data on the new pokemon.
Isshu
Isshu actually isn't a second region. If you've seen or heard about it well, it means Unova In Japanese!
The 5th generation region is called the Isshu region. The Isshu starters are Tsutaaja, Pokabu, and Mijumaru. The first games to feature the Isshu region and 5th generation Pokemon is called Pokemon Black and white versions in japan.
