Amazon will be the first foreign company to offer a prepaid wireless service in Japan. Nikkei [account required] reports prepaid SIM cards with 500MB preallocated to it will be sold for 1,980 Yen ($25) through the website, and as a mobile virtual network operator (MVNO), will be carried by NTT Docomo's LTE network. This takes place ahead of the expected Japanese launch of the Amazon Kindle in the Summer.
