PyCon JP 2025 Call for Proposals

PyCon JP is the largest international Python conference in Japan.

Conference Basic Information

Event Name: PyCon JP 2025
Dates: Friday, September 26, 2025 and Saturday, September 27, 2025
Venue: Hiroshima International Conference Center

Event Theme: “Pieces of Python, Coming Together”

Inspired by the Hiroshima International Conference Center, we take the word “pieces” as our starting point. We aim to create a space where the many “pieces” that support Python—technologies, tools, experiences, and people—can gather, connect with one another, and give rise to new possibilities.

Guidelines for Proposal Submission

Please submit your proposal in accordance with the guidelines below.

1. Adherence to the PyCon JP Code of Conduct

All participants in PyCon JP are required to abide by our Code of Conduct. Even if your content is excellent, any proposal that does not comply with these standards cannot be accepted. Violations include inappropriate references to or slander of specific individuals or organizations. Please read the Code of Conduct carefully before applying.

2. Clear Definition of Your Audience and What They Will Gain

PyCon JP attracts everyone from complete Python beginners to seasoned experts, working across a wide range of fields beyond just web development and data science. We value proposals that clearly align who you’re addressing, what you will teach them, and how you will deliver that content.

3. Genuine Motivation for Your Presentation

Tell us why you want to give this talk. Behind every presentation should be a sincere desire—whether it’s “I want to prevent others from facing the same challenges I encountered,” “I want to help someone,” or “I want to contribute back to the community.” We look for that genuine passion.

4. Relevance to Python

PyCon JP welcomes both light users and heavy users of Python. Today, Python is used by scientists, embedded into spreadsheets, and more. We consider any use of Python to be relevant.

Travel Grant for Participants

For presenters coming from outside the region, we offer travel and accommodation support through our Travel Grant Program. Details will be announced on the blog at a later date. As a reference, please see last year’s Travel Grant post:

FAQ

Q: Can I submit multiple proposals on the same topic?
(For example, a talk and a mini-talk both covering the same theme.)
A: Yes. We will try to avoid accepting multiple sessions on the exact same theme, but please note in the “Notes” field if you plan to submit duplicates.
