• Periodic Observation Report "Broadband Traffic Report : COVID's 3rd Year Brings Lull in Traffic"[3.18MB]

  In this report, we analyze traffic over the broadband access services operated by IIJ and present the results each year. Here, we again report on changes in traffic trends over the past year, based on daily user traffic and usage by port. Now in the third year of the COVID-19 pandemic, the solid increase in traffic we reported on last year has continued, albeit with the growth rate slowing slightly, and so far we see no noticeable changes in that overall trend.

• Focused Research(1) "Live-Streaming the Spring Festival in Tokyo—Our Report"[2.38MB]

  The Spring Festival in Tokyo is one of Japan's largest classical music festivals, held once a year at music halls, museums, and other venues around Ueno. In 2021, the festival went ahead under restrictions to prevent the spread of COVID-19—a maximum attendance of 5,000 or a 50% venue capacity limit—so to make up for the limitations on physical attendance, we live-streamed all 60 performances held across the 14 venues. In 2022, as in 2021, we live-streamed almost all of the 56 performances across 14 venues. With over 10 venues being streamed and some performance or other taking place every day over the festival’s month-or- so running time, on some days we streamed as many as four performances simultaneously.
