Red Bull suffered a mysterious lack of performance at last weekend's Singapore race, which led to both drivers dropping out of qualifying in the second phase as neither Max Verstappen nor Sergio Perez could improve on their final Q2 laps.
Perez had stated that Suzuka "should be one of the best circuits" for the RB19 package, which has been an exceptionally strong car in corners that require high-speed downforce and fast changes of direction.
Adding to Perez's comments, Hamilton ladled praise on Red Bull's current car and suggested that it should be "30 seconds" ahead of the rest of the field in race trim.
"I would think that if they're not 30 seconds ahead like they have been in the past, then something's up," Hamilton said.
"As Checo said, it was obviously a difficult weekend in the last one, but that car should be phenomenal here. They've been phenomenal all year long. They've aced pretty much every circuit.
"It's going to be great to watch that car in general. Normally you would come here and it's beautiful to watch the laps that they do. The whole team and the drivers are doing an amazing job with the package they have.
"It'll be interesting to see how the weekend goes. I hope we'll be closer, and I hope they're not as fast as the 30-second gap."
