Why have Japanese consumers not fallen in love with digital reading? “So far the Japanese have failed to be moved by e-readers from home or abroad, mostly owing to a paucity of content,” says editor and publisher of Japan’s E-book 2.0 magazine Hiroki Kamata. Sony (SNE), for instance, has been in the market for more than seven years but has sold only 500,000 e-readers in Japan. Other manufacturers’ tablets have begun to sell here, but overall the category is still way behind e-reader take-up in the U.S. or Europe. Tablet sales have tripled since 2011, with market research firm IDC estimating tablet sales in Japan to be 3.6 million units.

Japanese consumers still seem dead set against adopting e-books, showing less interest in them than even the print-worshipping French. According to an R.R. Bowker study, 72% of Japanese consumers said they had not tried e-books and did not want to try them. That compares with 66% of French respondents polled. Overall adoption rates in Japan remain the lowest in the developed world. Only 8% of Japanese readers have downloaded and paid for an e-book compared with 20% in the U.S.

Tokyo based e-publisher Robin Birtle notes that Japan is at least five years behind the West in terms of digitization. He says Japanese tastes may simply be different. “The Japanese do like to have something physical,” he says. That might explain why although Japan has some of the fastest Internet connections in the world and on-demand services, packaged, physical media such as DVDs still remains popular.

Japan has also been slow in getting the machinery of Japanese e-books whirring. There are just 40,000 titles available in most digital bookstores. “Publishers are indifferent to, or even hate, digital things. Mainly because of excessive commitment to traditional print book distribution,” explains Kamata. Japanese publishers are said to fear losing their long-held privilege of dictating prices. Amazon’s (AMZN) arrival — its first Japanese Kindle arrived late last year — notwithstanding, the publishing revolution appears stalled. Aya Murota, an analyst for the Tokyo office of the Hong Kong Trade Development Council, says it is difficult for Japan to change. “Japanese publishing companies are very traditional. Many of them are reluctant to change their whole business structure,” she says.

Much as elsewhere in the world, the battle over Japanese books is shaping up along conventional lines. Amazon is feeling pressure from Google (GOOG) and Apple (AAPL), both of which are poised to open e-bookstores for Japanese readers. The launch of Kobo e-reader, which is owned by Japanese company Rakuten, last July was marred by software issues.

Competition may emerge from an unexpected corner. “Whether or not a significant third player emerges is an interesting question. Apple are always a threat, and Microsoft’s (MSFT) investment in Barnes and Noble (BKS) may be enough to underwrite overseas expansion beyond Europe,” explains Birtle. ”The company to watch, though, is NTT Docomo (DCM) — Japan’s leading mobile network provider.” Recently the telecom giant announced it would be going head to head with Amazon in March with its own tablet the “dtab” – priced lower than the Japanese Kindle.

So, so far it’s tablets galore for the Japanese market. But with such meagre offerings in the way of content from the Japanese publishers, it will take more than shiny new gadgets to lure Japan’s avid readers away from their paper.
