Urban Rooftop Craft Wine Project: MaeVino's Bold Initiative

In a pioneering move, MaeVino LLC, under the leadership of CEO Keisuke Ashizawa, is embarking on an innovative venture that seeks to cultivate grapevines directly on city rooftops. This project, which is slated to begin operations in 2026 across Setagaya and Kawasaki, aims to transform underutilized rooftop spaces into thriving “mini-farms” for wine grape cultivation, fostering a new culture of craft wine that connects people and neighborhoods in urban settings.

Purpose and Vision of the Rooftop Initiative

The urban craft wine project takes aim at exploring the possibilities of growing grapes in non-traditional environments. MaeVino collaborates closely with Associate Professor Honma from Tokyo University of Agriculture, who provides expertise on suitable cultivation methods and operational strategies for the unique challenges presented by rooftop farming. This collaborative effort is directed at establishing sustainable urban vineyards that not only yield quality grapes but also enhance community interaction.

Participatory Winemaking Experience

MaeVino does not simply aim to sell completed wines; instead, it offers an engaging participatory experience for urban dwellers. Those who join the project can become 'grapevine owners' using the specially selected Maeve grape variety, which thrives in urban rooftop conditions. By participating, individuals will enjoy a range of exclusive benefits:

• - Observation of their personally named grapevines with dedicated identification plates
• - Invitations to several hands-on care events and harvests throughout the year
• - Delivery of community wine produced from the year's harvest

This unique approach allows participants to remain actively engaged in the winemaking process while enjoying their urban lifestyle.

Creating a New Wine Culture

The launch of the urban vineyard initiative marks how MaeVino envisions the future of winemaking in cities. Preparatory efforts for this project have been underway since 2025, focusing on planting grapevines and developing a conducive growing environment on rooftops within Setagaya. Through trial and improvement, they have steadily crafted a framework for urban residents to grow wine.

The 2026 season will see the Setagaya Vineyard officially in operation, with the grapevine owner recruitment already reaching full capacity of 30 slots. In response to the increasing interest and a broader call for participation, MaeVino plans to establish a new vineyard in the Kawasaki area starting in 2026. This expansion aligns with the aim to cultivate craft wines that highlight local elements and distinct urban characteristics.

Call for Rooftop Partners

To support the initiative and facilitate further expansion, MaeVino is actively seeking 'rooftop partners’—building owners willing to collaborate in establishing vineyards on their unused rooftop spaces. The project not only brings new life to these often-neglected areas but also fosters connections with residents and the surrounding community. Rooftop wine gardens offer an effortless way to engage in meaningful urban experiences without the need for mass events or extensive renovations. MaeVino takes charge of the installation and operations, ensuring seamless integration into the local urban culture.
