Osaka- probably one tackle shop worth of visit as the others is a bit difficult and a bit far to visit unless you have plenty of time to spare
1.Lure1ban ( dangerous for wallet) located near the osaka station about 5 min walk
They stock all sort of quality stuffs from
Popping ,jigging, lines, accessories, clothing to small lures, they have heapsssss of jigs especially the current trend one which is slow jig
Tokyo- plenty of sansui stores to visit but the one with most high end pop n jig stuffs located in shibuya
My 1 cent advise is go to shibuya from there, there are a few shops u cAn visit, and it takes time to visit each of them and browse them troughly
1. Jumbo (moderately dangerous)- 5 mins walk from shibuya station. they have mid to low end stuff mostly, but if u after some jdm shimano, daiwa clothing/ accessories thats the place to go plenty of shirts, t shirts, cap, jacket, etc where u wont find anywhere in the other shops in japan and probably any tackleshops in the world
2- sansui shibuya ( dangerous) about 15 mins walk from shibuya station-as i mention above they have plenty of high en pop n jig stuff, but there are a few sansui shops in closed range so make sure u visit the right one( check in their website which shops stock which thing)
3- if u have plenty of time to spare , then go To proshop mogi (very dangerous!). From shibuya station u need to catch train to azamino station which takes about 30mins one way. Well this shop no need any introduction i guess.
But i have a bad experience with the rude shop keepers during my visit. They speak no english what so ever, so just come take what needed n go
Most of sansui stocks the same thing only minor different on the high end stick baits
4.tackle berry(moderately dangerous) they located right behind jumbo, they stock mostly discounted
And used stuff, but worth a visit as u mignt find something unusual there
Shinjuku- sansui shinjuku( moderately dangerous)about 10 mins walk from station
Ueno- sanaui ueno( moderately dangerous) about 10 mins walk from ueno station
I hope this help
