Both T1/T2 felt the same to me when i transited a few weeks ago. Shops/duty free are on an odd schedule and open late or at staggered/inconsistent times. I mostly did lounges for food, but i do know that the 7-11 at T2 was hopping!

NRT posts the hours of shops on their website, but YMMV as per usual https://www.narita-airport.jp/en/news/coronavirus_shops
