is former Air Nippon JA8761, cn 2133. A source for questions like this is http://www.airlinerlist.com
Amazing colours, never thought they'd adopt the Metrojet colours, but must admit it's nicer than their original scheme. Might be a nice separate thread; which airlines chose a new scheme because they liked the colours of 2nd hand planes they bought. I can think of Dinar Argentina who adapted Crossairs old colours, or JAS in Japan who took over the Airbus house colours.
