You really need to understand the market before you start operating there. Take Amazon's case for instance, which has found itself in the middle of a backlash with publishers in Japan. When Amazon launched its "all-you-can-read-subscription" Kindle Unlimited service in Japan, the company didn't know it would become such a big success. And yet it did. So much so that Amazon had to sharply scale back within weeks of its introduction in the country. Before Amazon introduced the feature in Japan, it partnered with Japanese publishers to offer their popular content, committing to pay them a premium through the end of this year when a customer reads at least 10 percent of a book or other content. It worked -- too well, WSJ reports. From an article: Since it's easy for readers to get through the first 10% of a magazine or photo book in just a few minutes, Amazon quickly found itself on the hook for large payments (Editor's note: the link could be paywalled; alternate source), a person at one publisher said. A person at another publisher said Amazon made an overture for talks in September saying it had hit its budget limit for the payments to publishers and wanted revisions to its contract with the publisher."
