England took the lead in the 19th minute with a header by Taylor Moore and a minute later Adam Armstrong ghosted through the Nigerian defence for the second goal.
Thereafter, the Eaglets defence caved under waves of attack as Dominic Solanke and Armstrong added two goals in the 25th and 28th minute.
Abdulrasaq Yusuf pulled a goal back for Nigeria with a well –taking shot in the midst of legs in the 35th to keep scores 4-1 in the first stanza.
At the beginning of the second half, England continued where they left off in the first period with two quick goals through Callum Connolly and Patrick Roberts in the 46th and 49th minute respectively.
Armstrong got the first hat trick of the tournament in the 70th minute and Roberts his second within minutes to spare to push England on top of the table on better goal difference after hosts Korea beat Iran on Tuesday.
Nigeria and Iran will slug it out while Korea will tackle England in the next round of matches at the same venue on Thursday.
