Okay, so no bread crumbs for me to follow so I'll leave a trail.
I had 5 free hours in Osaka and learnt about Shinsaibashi, a district of high-end retail shops. Having only the address of the Beams store I exited the subway at Shinsaibashi station and found an English speaking subway employee who provided me a neighbourhood map and pointed me in the right direction. On my walk to Shinsaibashi I visited the the shops of JM Weston, Berluti, and Regal (a well-known Japanese shoemaker); all shops on street level. I also stopped at a tailor shop named either Strasborg or Strausborg that sells Edward Green shoes; the men's store is on the 2nd floor and the women's store is on the ground level. (A word of warning. The sidewalks are also used by numerous bicyclists who pass you at a fast pace with no warning such as bell, horn, or voice. I almost was creamed a few times. For you pervs who enjoy up-skirt panty viewing many of the female cyclists oblige by wearing quite high miniskirts.) Key landmarks to look for are the Louis Vuitton, Max Mara and Dior shops. The Dior shop is a key one to locate because the Shinsaibashi covered shopping arcade / pedestrian mall is the lane behind it. There are several hundred shops in the arcade.
First up is United Arrows in the Daimaru Department Store - there are 3 buildings and United Arrows is located at the North building: http://www.united-arrows.jp/en/shop/uss.html
. United Arrows has several boutiques in this store. The main men's one is on the ground floor,and there is also another men's boutique on the 2nd or 3rd floor. After you purchase your items, and you have your passport with you, go the the tax refund office on the 5th floor. You'll get 5% back. Be prepared to queue.
Continuing my stroll (I'm assuming south) in the Shinsaibashi pedestrian arcade I found these shops that may interest you.
1) Journal Standard, http://journal-standard.jp/mens/
2) Urban Research, http://www.urstore.jp
3) Rose Bud, http://www.rosebud-web.com/shop/rosebud/item/list/category_id/2
. Mostly women's clothing but a small selection of men's.
4) RL Denim and Supply. Yes, this is RL's low-end stuff, and quite pricey, but the store was impressive.
5) Wego, http://www.wego.jp/
This is multi-floor and very cheap store. There is one entire floor of vintage clothing if that's your thing. I recall used Dr. Martin's boots are priced at approx. $75.
Once you reach the river you're finished with the Shinsaibashi shopping arcade, but there's still plenty to see all over the place if you have the time. Walk one block to the main street that runs parallel to the arcade, I believe this is Mido-suji street. Walk north (back to the Dior shop where you started) and you'll find the Beams Store. This store is definitely worth your visit, http://www.beams.co.jp
. They gave me a 5% discount right at the counter for being a foreigner; the clerk said if I'd take my receipt to the Daimaru Department Store I'd also get the tax refund, but I didn't have time to do that again.
I didn't have time to dig into Umeda, Namba and Amerika-mura. What I read there seems to be much to be found in those areas too.Edited by curzon - 10/4/14 at 9:51pm
