This is one of the "Triple Threat" challenges in this game. This means the chart is on Extreme difficulty, and three modifiers get applied at the same time. In this case, it's the one that makes the notes smaller, the one that hides the timing of the notes, and I think the one that makes the notes appear later. So aside from the song being the easiest in the game (since it's the first one lol), this modifier combination is quite easy to deal with too.
This song is also known as ハジメテノオト (HAJIMETE NO OTO).
