On April 23, Yodobashi Camera announced through their online sales site "Yodobashi.Com" and their telephone sales service "Moshi Moshi Yodobashi" that they are discontinuing sales of Apple products. Sales at their retail stores will still continue.
According to Yodobashi Camera, "it has become the case that [they] can no longer sell any Apple products, including iPods, MacBooks, iMacs and related accessories." Furthermore, they say that it was "according to the wishes of Apple."
Customers can continue to use the "store pick-up" service where they order an item online at Yodobashi.Com and pick up the item in person at a store. They can also continue to determine whether a product is in stock through their "in stock inquiry service."
"We have no comments beyond what has been said online" is the statement from Yodobashi Camera.
With regards to online sales of Apple products, many other high volume retailers such as Bic Camera and Yamada Denki have similarly stopped. Bic Camera also stated that they cannot comment on what led to this, but vehemently state that "since you can pick up ordered items at the store, we don't believe it should be that big of an issue."
In addition to high volume retailers, Mac-specific small-time shops "Akihabara Mac Collection" and "kitcut" that were selling Apple products through Rakuten [an online market place in Japan] have also stopped sales. (However, kitcut as of this writing, April 26, still continues selling products on their own site.) Furthermore, upon seeing many Rakuten shops having marked [Apple items] as "out of stock" or "no longer available", one might be able to say that this issue is a life and death situation for online shops who do not have physical storefronts.
With so many retailers stopping online sales of Apple products, Apple's very own "Apple Store" still continues to sell them, unsurprisingly. Furthermore, the foreign-owned Amazon continues to do so as well.
As of April 26, Apple has not made an official announcement and refuses to comment on the situation.
