Standing spaces built specifically for hikikomori siblings are vanishingly rare in Japan (marked ✦ on this page). That's exactly the gap this project documents — and it's why siblings have found their footing on the neighboring shelves: disability-sibling groups, mental-health-sibling groups, young-carer communities. This page maps all of them.
✦KHJ Sibling Online Branch — Monthly Zoom Circle
A monthly, confidentiality-first facilitated Zoom circle chaired by journalist Ikegami Masaki — himself a sibling. Joinable from anywhere in Japan; each session requires advance signup (Peatix, deadline the day before; email fallback). Handle-name participation is fine — facilitator Saitō, branch chief Ikegami.
🕐 月1回・主に日曜 19:30〜21:30(月により土曜 20:00〜22:00)・500円。Peatix申込(締切は前日)/メール online-kyodaishimai@khj-h.com (Check official site for current hours)
💴 ¥500
Website ↗Sibkoto — The Siblings' Platform
Built for siblings of disabled people, but explicitly home to hikikomori-sibling content too (it hosted the KHJ sibling-group interview series in our index). Read, post, and find sibling events in one place — the front door to Japan's sibling community. Also hosts a nationwide directory of sibling groups at sibkoto.org/siblings.

Website ↗Hikikomori UX Kaigi — Event Calendar

✦SHIP — Network for Hikikomori & an Inclusive Society

A media-and-dialogue network, with the quarterly magazine SHIP!.
