There seems to be a common assumption that people gravitate towards collecting Japanese over time. It is treated almost like an inevitability by some people in the hobby, that English is a stop gap on the way to Japanese.
It is a reasonable enough narrative that might be demonstrated by many in this community, but I think if we are talking about the entire market as a whole then the reality is much more complicated.
First, I think we can all agree that greater depth and engagement in the hobby is required for one to even learn about Japanese cards, especially the many exclusives, since most of us did not grow up with them. That knowledge is a barrier that countless many collectors may never cross. A community such as this is its own bubble filled with people who actually took that deep dive. It is not necessarily the obvious end journey.
Second, just because one gains the knowledge and appreciation for Japanese cards does not inherently mean they will shift their collection priorities in that direction over time.
It is commonly said that people coming back to the hobby might start with ultramodern, then revisit their childhood (probably English sets), and then take one of the deeper dives, possibly into the niches of the hobby.
What I think some people might not fully appreciate is just how hard the “revisiting the childhood set cards” actually can be. As a kid I was around for and I opened all WOTC sets.
Personally, I have a goal of getting every 1st Edition WOTC holo in PSA 9. After that I probably want to expand that to all WOTC cards in PSA 9, including the promos, non-holos, and reverses. Basically my goal is the PSA 9 version of what Gemmintpokemon achieved in PSA 10.
That is a massive goal that could easily occupy me for the next decade… or more.
Yes I appreciate Japanese, acknowledge its uniqueness, and admire its exclusives and trophies and print quality and all its other positives. However, my nostalgic connection to English WOTC and hugely ambitious goals there make it impractical for me to branch out anytime soon in any meaningful way.
I realize this is an anecdote, but I do think it is worth remembering that there may be many other collectors out there that have a goal similar to mine, whether it be raw or graded. English might not have the same endgame or difficulty as Japanese, but it can still become an immense journey in its own right.
This probably only loosely relates to the topic at hand (whole market trends and shifts between English and Japanese), but it’s something I’ve felt should be expressed, as another perspective on the common narrative that I see posted all the time.
