Sessions: IGF 2016 debrief (26 Jan, 16:00–17:45, JPNIC conference room, held back-to-back with the 17th IGCJ meeting)

• Eleven participants — including MIC's Makoto Takamura, JPNIC's Izumi Okutani and JAIPA's Toshiaki Tateishi — reported on IGF 2016, held in Guadalajara in December 2016, from government, technical-community and business perspectives [2][4]
• The debrief relayed in Japanese the debates of a meeting that drew some 2,000 participants from 123 countries; the 17th IGCJ meeting that followed took stock of the year and discussed IGCJ's future [2][4]

2. IGF-Japan 2017 — Governance after the Transition, and Zero-rating

Sessions: IGF-Japan 2017 (7 March, Toshi Center Hotel Room 606; hosted by JAIPA, supported by MIC)

• As the first domestic forum after ICANN left US-government oversight, it took stock of IGF 2016 and the implications of the IANA transition [4][5]
• Net neutrality — above all the pros and cons of 'zero-rating', which exempts specific services from data charges — was a headline topic [4][5]
• Youth IGF programmes ahead of APrIGF Bangkok (July 2017) also came up, putting next-generation capacity building on the domestic agenda [4][5]

3. Securing the IoT Era — Practitioners and Officials on One Stage

Sessions: 22nd meeting, Part 1: 'The security and IoT landscape' (30 Nov, during Internet Week 2017)

• Practitioners from across the security ecosystem — Yahoo Japan's Kenta Mochizuki, Microsoft Japan's Ken Katayama, APNIC's Pablo Hinojosa, NICT's Masaki Kubo, JPCERT/CC's Shingo Abe, MIC's Atsushi Goto and NTT Communications' Satoshi Noritake — debated side by side [3]
• Against the backdrop of exploding IoT device numbers, the session examined security governance from operators' incident response, international cooperation and government policy angles [3]

4. IPv6, Warts and All — Content Providers Speak Frankly

Sessions: 22nd meeting, Part 2: 'IPv6 today from the perspective of content and data-centre operators and government'

• Content and data-centre operators including J-Stream and DMM.com Labo spoke frankly about the realities and hurdles of IPv6 adoption (moderated by JPNIC's Masayuki Okada) [3]
• A hands-on session true to the resource-management community, digging into why migration stalls — without the usual pieties [3]

Three-Minute Short Talk — Your Questions Answered

Q. What were the highlights of Japan's 2017 governance debate?

A. The IGF 2016 debrief in January and IGF-Japan 2017 in March. The centre of gravity shifted to running the internet in the world 'after' the IANA transition completed the previous year.

Q. What's the problem with zero-rating?

A. It makes traffic for specific apps free of charge. Convenient — but should carriers get to pick which services to favour? That question cuts to the heart of net neutrality.

Q. Why should I care?

A. Neutral pricing on your phone plan, the safety of IoT gadgets at home, the quality of your video streams (IPv6) — 2017's agenda was everyday life. And every venue was open for anyone to join.
