Weathernews Inc. (ja:ウェザーニューズ?), a weather information company, started a paid service to broadcast EEW for advanced users, The Last 10-Second, used by people and businesses on 15 October 2007.[35][36][37] This service requires a computer running Windows 2000 or later with an always-on connection to the Internet and offers an affordable alternative to a costly communication terminal used exclusively for EEW. The EEW application installed on the computer can be configured to receive information on all earthquakes with a JMA magnitude of 3.5 or higher or with a seismic intensity of 3 or higher. Newer versions of the program allow for the announcement of lower-intensity earthquakes. When an EEW warning is issued, the program will announce the approximate location of the epicenter, the expected JMA seismic intensity and display a countdown of when major shaking is to be expected. On 7 July 2008, ANET Co., Ltd. (ja:ANET アネット?), a disaster prevention technology company of the Railway Technical Research Institute Group, released an application, EQMessenger, to receive ANET Alert, which ciphers and broadcasts EEW information on the epicenter, the estimated seismic intensity at the user's location, and the remaining time before the arrival of the S-wave.[38] When the estimated seismic intensity exceeds the preset level, EQMessenger can sound a warning and display the epicenter, the intensity estimation point, and the arrival of the tremor on a pop-up map. After the 2011 Tōhoku earthquake, a similar Windows program was made available for free by the Strategy Corporation (ja:ストラテジー株式会社) called SignalNow Express.
