What does “gain-Y” come from?

gain-Y (pronounced “gai-ni”) comes from the word gaini (がいに) in the local Sanuki dialect. In Kagawa, gaini means something amazing. gain-Y combines the gaini from Sanuki dialect with gain from English. The Y on the end represents our mission to make people happy- “wai wai” in Japanese.
※Sanuki dialect uses gaina and gaini, but gain-Y is our original spelling.



Coworking Space

Coworking means working together, not just as employees. Ideas, information and technology are combined and shared to create synergistic results in a new working style.
Co-working spaces became popular around 2006 among internet-related businesses in the San Francisco area; and 2010 brought the first co-working space in Japan.Most co-working spaces are in the Tokyo area, but gain-Y is the first in Kagawa



The Difference Between Share Offices & Rental Offices

Business development and incubation facilities tend to be set up as a series of private rooms, missing the essential elements of a social atmosphere and creative collaboration.

What Makes gain-Y Special?

gain-Y offers each member an individual presentation BOX (30x40cm.)Even though each member works on a unique schedule, each BOX displays the story of that member’s work project for other members to browse.You’re sure to find a colorful BOX that catches your interest.


gain-Y prioritizes member communication.We believe that all work requires a trusting relationship – as members gain deeper trust in each other, individual projects blossom into group work, paving a path for bigger ambitions in the future.Work brings many opportunities, but not everything can be accomplished alone. We believe that when gain-Y members assist with each other’s projects, the deep trusting relationship creates a foundation for more thorough work and greater opportunities.


There are many different ways to enjoy gain-Y’s facilities: as a second office, as a spot for personal hobbies, or even as a location for seminars and workshops.
