In Japan, regular donors, often referred to as “Monthly Supporters,” play a vital role in ensuring consistent revenue streams for nonprofit organizations. By contributing a fixed amount each month, these supporters help sustain essential nonprofit activities. Leading organizations like UNICEF Japan and Médecins Sans Frontières Japan have significantly benefited from regular giving, with nearly half of their individual donation revenues stemming from such supporters. This approach, combined with unique fundraising strategies tailored to the Japanese context, has become an essential pillar for many nonprofits in the country.
