TAKESHI HIRATSUKA 平塚 武
Turning data and AI into something people can use.
Turning what I learn into someone else’s next step.
Good data.01 / COMMUNITY, AT THE CORE
Share the knowledge. Create the conversation. Help someone take their first step.
Community is at the heart of how I work.
Good questions.
Better, together.
I’m building a place to bring Data 360 and AI questions, practical experiments, and lessons learned across companies and experience levels. A community for newcomers and practitioners to learn, build, and connect.
Independent and practitioner-led. Not an official or endorsed Salesforce community.
EVENT DESIGN & ORGANIZATION / SERIES LEAD / SPEAKING
With JTUG and KTUG, I lead the Tableau NOW! / Tableau New Era series: an ongoing conversation about Tableau Next and BI × AI, connecting Tokyo, Osaka, and online audiences.
Explore the event series ↗COACHING / OPEN RESOURCES / JAPAN ⇄ GLOBAL
From coaching 300+ beginners to publishing practical decks in English and Japanese, I work to connect Japan’s Datablazers with the global DataFam and help the learning reach the next person.
Take something useful with you ↗An entry point for newcomers and practitioners. The published program lists Takeshi for the Data 360 overview, Slackbot integration, and discussions on BI and data activation.
Organizer’s event page & program ↗I lead and speak in the Tableau New Era / Tableau NOW! series, a recurring community forum for exploring where BI goes next as Tableau Next, AI agents, and semantic data models move from frontier concepts into practice. JTUG is the Japan Tableau User Group, and KTUG is the Kansai Tableau User Group.
Tableau Next × Slack
Our Tableau Next and Slack implementation at Leave a Nest is published as an official Tableau customer story. With Tableau Semantics, ten years of mature, highly customized Salesforce data became AI-friendly so 150 employees can ask questions and act on trusted insights without ever leaving Slack.

k.lne.st →Born in 1980, I started in core systems development and data platform engineering. After leading business-systems adoption at SmartNews, I joined Leave a Nest Knowledge (the group's Salesforce consulting arm) in October 2023, where I serve as a board member.
My specialty is unified data architecture on Salesforce Data 360 (Data Cloud), Tableau Next, Slack, and Snowflake: the three-layer path from data lake to data model to semantics, designed so that both people and AI agents can act on trusted data. My personal mission is to grow organizations that can truly use AI and IT, not just install them. I try to give back to the community that raised me by learning in public and coaching the next generation of data beginners.
Outside work, I study art history at Kyoto University of the Arts and enjoy visiting museums. I can’t live without manga, movies, and live shows by the galactic punk band Wienners.
