Washi origami paper at Narita Terminal 2 (after security and passport control)

I will be coming into Japan from Seattle (US) and have a 3 hour layover at Narita terminal 2 before my next flight to Bengaluru (India). I will not be passing through passport control and I don't have a Japanese visa.

I am looking for shops from where I can buy Washi origami paper. Based on my research all the stationary shops are before passport control. Is that correct?
