お茶会 · Activating Urban Connections
Residents who support one another.
Neighbours who can rely on each other.
Ochakai helps organisations build resident-led community systems and hands them over to residents to sustain independently.
Our work · お茶会の活動
We are not an event provider.
Ochakai designs and runs structured, time-bound pilots that give housing organisations a replicable system for everyday neighbour connection, one that residents can continue running themselves after the pilot ends.
Why this matters · なぜ
Working upstream, before issues surface.
Residential buildings bring many people into close proximity, but rarely create the conditions for natural interaction. Over time this leads to low neighbour familiarity, limited informal support, and higher reliance on formal services for small everyday issues.
Ochakai works upstream, before those issues surface, by creating the conditions where connection can emerge and sustain itself.
How it works · どうやって
The Neighbour Connection Pilot.
The Neighbour Connection Pilot runs for 8–12 weeks. It introduces lightweight structures (small gatherings, shared communication spaces, recurring touchpoints) that make it easier for residents to meet, recognise one another, and gradually build familiarity.
By the end of the pilot, the system belongs to the residents. Not to Ochakai.
This is a system activation process, not an event series.
Proof it works · 過去の事例から
A pilot in The Hague that outlived our involvement.
In The Hague, Ochakai ran a pilot in a residential building where neighbours rarely interacted. Simple structures were introduced: a shared picnic in an unused courtyard, a neighbourhood tea session, a resident communication group.
Within weeks, over 30 residents had joined the communication channel. Within months, residents were organising follow-up events themselves without prompting.
One year after Ochakai's involvement ended, the gatherings were still happening, organised independently by a resident who had never done anything like it before.
Programmes end when funding ends. Systems, once established, can persist on their own.
What organisations have observed
- Increased familiarity between residents.
- More frequent informal greetings and interactions, observed even a year after implementation.
- Small acts of mutual support emerging naturally: lending items, helping with small tasks.
- Improved ease of everyday communication within the building.

Who we work with · 誰と
Housing organisations and municipalities open to testing.
Ochakai works with housing organisations and municipalities that have an active interest in liveability and tenant wellbeing, and are open to testing a structured, evidence-based approach in one or two buildings.
We bring the methodology, the facilitation, and the learning framework. You bring the context, the residents, and a shared commitment to understanding what works and what persists.
About · お茶会について
Ochakai was started by Aya Toriyama in her own residential building in The Hague in 2024, after noticing how rarely neighbours connected despite sharing the same physical spaces. It grew out of research into urban belonging and everyday social infrastructure at Erasmus University / IHS, and from years of cross-cultural community work across Japan, the Middle East, and Europe.
