Tanaka admits Leeds players are happy with the way they've started the season.
He told PLP: “We did well, we did well.
“But of course, we have to get points as much as possible and we have to win, especially at home. So, yeah, we have to keep going.
“Especially in the Premier League, every team is at such a high level so it is not easy to win the game. It is not easy to get a point, one point, but we just focus on the details. This is important for the Premier League.
“Small things are like every team has so much quality, especially with set pieces as well, long throws as well. This is important, so I need to learn a lot of things.”
On welcoming West Ham to Elland Road, Tanaka added: “It is a good team I think and they have played a long time in the Premier League, so it is not easy to win this game but you have to focus.
“I think this game is a little bit different because against Everton as well, we play a night game and then I think it was incredible, unbelievable.
“If we get a chance, if we play good, it makes so much good feeling here (for the crowd), so this is important for us to win this game.”
