ZIPAIR RT Non-stop flights: LAX-NRT $427.00

i just got a notification from Google flights that ZIPAIR just dropped their prices for Nonstop flights from LAX to NRT.
I see some dates from Nov-Dec and almost all months of Jan-Feb. search for more than 3 days to get the prices. ZIPAIR is a low-cost airline but for $427 round trip Nonstop is not bad.
