Star Alliance member EgyptAir is offering business class flights from Budapest to Tokyo starting at €1,548 (~HUF 550,346). You can find these departures in late July and early August, with additional dates available for €1,650. The itinerary includes a 5-hour layover on the outbound journey and an 8-hour layover on the return.
EgyptAir is a dry airline, so no alcohol is served on board. On the plus side, the flight to Tokyo is operated by a Boeing 787, meaning you will have a lie-flat seat from Cairo to Tokyo.
