Russia are the third team participating in the Sept 5-10 tournament along with the War Elephants and hosts Vietnam.
Ishii is aware of the tough challenge the FIFA Day break event poses, reports the Bangkok Post.
“Both Russia and Vietnam are very strong teams, but we must focus on ourselves,” said the Japanese tactician.
“We are planning to get some young blood in the team as this tournament could serve as a great opportunity for them to show their talent and step up to become a permanent part of the national squad.
“First we need to follow the top players in the Thai leagues and assess their strengths and weaknesses.
“We normally don’t get enough time to train players for such tournaments, I’ll try my best to make them understand the tactics.
“These young players are bound to gain a lot of experience by playing against teams like Russia and Vietnam.”
On the opening day of the event, Vietnam will take on Russia on Sept 5, with Thailand facing the European side two days later.
The last match of the event will be a clash between regional arch-rivals Thailand and Vietnam on Sept 10.
