In a nut shell the Japanese have a tendency to keep the best for themselves , if you compare a JDM model reel to a USA model you will see what I mean. Not to confuse you but there are reels coming over now that are the same (i.e.13 Shimano Antares). So to some regard you have to watch and see what will come over and what will not like the new Antares DC for example. The best thing you can do is google JDM Fishing and start to educate yourself and ask questions about things you do not understand. Believe me it can be a fun trip to take while you learn more about their approach to our shared sport of fishing .
The other big thing to me is lures/baits of all kinds hard to soft , crank baits , topwater, bugs you get my point. Check them out and you will be amazed to see what is available . Color is a big thing to me as over the years I have found that JDM color schemes work best for me. And again they keep the best for themselves so have some fun checking it out and see if it is for you.
