JDM (Japanese Domestic Market) tackle in not necessarily higher quality than internationally available gear. Some JDM reels have fewer ball bearings or lesser quality steel bearings. Their lures for estuary fishing will be fantastic. Japanese love anything finesse and shinny. But again not necessarily cheaper and if you need to upgrade hooks and rings maybe even more expensive. I bought heaps of squid jigs but not much else. Do some homework before you go. Do your money conversion equations and currency exchange/credit card/cash card costs. I spent about 2 hours one day in 1 shop and only bought 2 things. Attached is a pic of 1 isle that just had floats, do the math these floats are $13 - $18 each 3 or 4 on each post, 30 or so posts in a line and 9 or 10 posts in each vertical = between 10k - 20k just worth of floats in this pic.
