Amazing. Thanks!! I also had Hal’s and Nakano on my list, but this is a great resource (recognizing some might be out of date)
Hal's is great, it's his son running it now, but selection can be limited and prices are up, the dude from Seeed in Osaka also a nice guy. ArtRock in Kyoto is good but haven't been in awhile, - HMV Shinjuku just moved to a new location that kinda sucks, also the HMV retail stores are really moving to new product only - have to say Disk Union is really the only place I buy records, I like Judgment Records as Hanawa-san is another OG jazz legend, but his prices have gone nuts - - koenji is a dope little town so worth visiting Ogawa-san, he's chatty and likes tourists, but don't expect to walk away with any minty treasures (personally I think he grades way too aggressively, been saying this for a while). pro-tip Disk Union doesn't list new releases on their website for a week (I think as ive definitely seen things in the new release bins that aren't online) so you may luck into some stuff. There's also a Jet Set in Shimo-kitazawa so you don't have to go to Kyoto for that, but their stuff is basically all new. If you've got cash and want to spend on the best stuff go see Jaro, but he's hard to deal with and find stuff and have to pay in cash.
overall record buying in Japan isn't what it was even 18 months ago (forget 20 years ago when I started going), most of the stores are filled with tourists and prices are high so regular Japanese can't afford to buy as much. I hate to say it but its also starting to get really picked out on used vinyl (quality down, prices up) and smaller stores are basically using discogs to price - lately ive been looking for super cheap stuff that sounds awesome outside of Jazz and Soul genres....or pick up some used Luxman gear while the dollar is still strong...but Japan is no longer cheap ;-(
but its a wonderful place to visit and your are guaranteed to have an amazing time!
Glad you're enjoying the Sullivan record it definitely smokes!
