Activity status, location, fees, recruitment, and services offered may change. Please check each group's official page for the latest information before taking part.

The listing order does not indicate ranking. We do not publish information we cannot verify.

Key points (30 seconds)

- Choose an IT engineer community by one of four purposes: learning, networking, speaking, or region

- This article introduces nine nationwide and six regional communities, including Kyoto's Miyako de IT

- Activity at all 15 was verified through primary sources such as official websites and connpass for 2025–2026 (detailed check on July 10, 2026; major official pages rechecked July 11)

- The order is not a ranking; it is organized as guidance by purpose and region

- Begin by creating a connpass account. Events marked “listening only is welcome” and co-working study sessions are accessible entrances

When you look for a community for IT engineers, what matters is less the number of names than whether a group is still active and whether its purpose and format match yours.

This article lists groups whose activity since 2025 could be confirmed on an official website or an official event page, organized by purpose: learning, networking, speaking, region, and specific technologies. It was compiled from 7 years and 153 sessions of operating the Kyoto IT engineer community Miyako de IT.

This is not an article that covers every community in Japan. A group that meets often is not necessarily suited to beginners. Check its recent events, code of conduct, fees, and the region where it meets before choosing.

For the underlying questions—what an IT community is and what participation provides—read The Complete Guide to IT Communities first. This catalog focuses on specific organizations.

Choosing an IT engineer community—four purpose axes

The first thing to decide is your purpose for taking part. Once that is settled, the candidates narrow naturally.

1. Learning—deepen a specific technology

For AWS, Azure, Python, PHP, Vue.js, Kubernetes, or another technology, its user group is the first candidate. Practitioners using the same technology can understand precise questions and share field knowledge.

2. Networking—find peers who can talk about technology

General communities and those centered on co-working or networking suit this purpose. For remote IT engineers with fewer contacts outside work, recurring face-to-face meetings provide value beyond learning. Remote IT Engineer Loneliness and Five Responses discusses this further.

3. Speaking—build a record of output

Choose a community with recurring lightning talks. You can progress from a five-minute talk to a regular meeting and then an annual conference. Candidates include the lightning-talk-centered IoTLT and communities with conferences such as Vue Fes Japan and JAWS DAYS.

4. Region—participate continuously near home

If continuity matters most, a community within traveling distance is practical. Kyoto, Kanazawa, Hiroshima, Fukuoka, Sapporo, and cities nationwide have continuing groups. Online participation provides additional choices outside major cities.

Listing criteria—verifiability, not a recommendation ranking

The criteria for listing are not name recognition or member counts. We selected groups meeting the following conditions, while avoiding an excessive skew in technical area, purpose, or region.

• An official site or an official event page exists
• An update date or recent activity can be confirmed—in this article, activity during 2025 or 2026
• The intended participants, event format, and how to take part can be confirmed from primary sources
• We do not rely on reposts from other sites alone
• We check for closure, suspension, and relocation
• We state whether listings can be paid for; this article has no paid listing slots
• When we list ourselves or a related group, we state the role and the relationship
• The listing order is not treated as a ranking

“15 with confirmed activity” better preserves accuracy and updateability than a stronger heading such as “the 15 best.” Numbers are not used as evidence of scale or superiority.

The items we check for each group

For each group, we check the following items.

• Name
• Main themes
• Intended participants
• Event format
• Main region
• The most recent activity we could confirm
• Official URL
• Date last verified
• Points to note on a first visit

In the body, the main themes, intended participants, event format, main region, most recent confirmed activity, and official URL appear in each group's entry. The date last verified is given in “Update policy” at the end, and the points to note on a first visit are collected in the “accessible entrance” column of the quick reference and in “Getting started.”

About listing our own community

Miyako de IT, which edits this article, is also one of the groups listed. It is an IT engineer community in Kyoto, run since 2025 as an official business of Netsujo Inc. (Shimogyo Ward, Kyoto). We do not rank it against other groups and describe it under the same items as everyone else.

How to find regional communities beyond these six

Cities nationwide have continuing communities. Search connpass for “city + co-working study session” or “city + study group,” or for regional-technology names such as “city.rb” and “city.js.” To launch one yourself, see How to Start an IT Community in a Regional City; The Complete Guide to IT Communities provides the broader search framework.

Getting started—four steps to a first visit

Step 1: Create a connpass account

Many Japanese IT communities recruit through connpass, though some use Doorkeeper or Luma. Search by technology and region, then join a community's group page for new-event notifications. Choosing Between connpass, Doorkeeper, and Meetup compares platforms.

Step 2: Choose “listening only is welcome” or a co-working session

Lower the barrier by choosing a format without required speaking. A seminar or a session where everyone advances their own task is complete through attendance alone. Look for “first-timers welcome” and “listening only is welcome.”

Step 3: Register and arrive at the organizer's specified reception time

Most events are free. Reception times vary, so follow the event page rather than a universal rule. Arriving slightly early creates time to tell an organizer that it is your first visit, allowing them to guide or introduce you.

Step 4: Do not judge after one visit; return and assess fit

Attend the same community several times. Faces, names, and conversation openings grow with each visit. If it still does not fit, simply try another; there is no reason to feel guilty about leaving.

For a first step in Kyoto or Kansai, try a Miyako de IT co-working session.

Taking a first step in Kyoto

Miyako de IT holds co-working and networking events once or twice monthly in Kyoto. First-time Visitors explains what to expect.

Frequently asked questions

Q. Does participation cost money?

Most regular study groups and co-working sessions are free. If drinks, a social gathering, or venue expenses require payment, the event page states it in advance. Large conferences such as Vue Fes Japan and JAWS DAYS may require tickets.

Q. Can I belong to multiple communities?

Yes. A nationwide specialist community plus a regional community in your daily area is a practical combination of learning and continuity—for example, building a work rhythm at a local co-working session and traveling to specialist conferences several times a year.

Q. Should I begin online or in person?

Both have advantages: online reduces travel, while in-person events are more memorable and build familiarity faster. One sequence is to learn the atmosphere through hybrid communities such as IoTLT or Kubernetes Meetup Tokyo, then attend a regional community in person. Include some face-to-face participation to support motivation.
