For Immediate Release

IIJ launches a trial environment for the IIJ Smart Metering Service for B-route
TOKYO—June 16, 2015—Internet Initiative Japan Inc. (IIJ, NASDAQ: IIJI, TSE1: 3774), one of Japan's
leading Internet access and comprehensive network solutions providers, today announced that it has launched"IIJ Smart Metering Service for B-Route" on a trial basis for electricity retailers and M2M and IoT solution
providers to test a system platform for offering services that utilize smart meters. IIJ announced thedevelopment of this platform in a press release issued on February 19, 2015 *.
* For more information, see this announcement: http://www.iij.ad.jp/en/news/pressrelease/2015/0219.html

There are two communications routes used with smart meters that electric power companies (called "generalelectricity utilities") are increasingly having installed in homes and offices: "A-Route," which is employed bygeneral electricity utilities, and "B-Route," which allows the acquisition of electricity data at shorter intervals
and in fine detail. By using the B Route, smart meters become electric power sensors installed at individualresidences. It is expected that combinations of B-Route-collected data and other sensor data will create newservices and businesses that employ M2M and IoT.
Already, a total of 10 customers—including KOKUSAI KOGYO CO., LTD. and TEN FEET WRIGHT
INC.— plan to use the new trial environment. The use of this trial environment—by both electricity retailers
and companies aiming to develop new services that employ meter data—will take advantage of theopportunity that the liberalization of electricity retailing presents and will lead to the creation and growth ofnew markets. IIJ continues to accept applications to use the trial environment.
