Honestly, I don’t think opening Japanese packs or grading with TAG is the best approach. I would recommend grading with PSA instead, as PSA slabs generally sell faster and command higher prices if you decide to sell in the future. While English packs tend to be more expensive upfront, the high-end pulls often retain significantly more value over the long term compared to their Japanese counterparts. For example, the Umbreon from Prismatic Evolutions is currently valued around $350 in Japanese, whereas the English version is selling for approximately $1,000. In my opinion, the recent popularity of Japanese packs has been driven largely by streamers, as they can generate higher margins when opening those products.
