Every exchange is made possible by the San Mateo community: families, neighbors, local businesses and volunteers. Your support pays for uniforms, travel, culture classes and hosting Toyonaka's visiting teams and students. San Mateo Sister City Association is a 501(c)(3) nonprofit (EIN 94-1588552), so your gift may be tax-deductible.

Corporate sponsorships
Companies can sponsor a team, a trip or a whole program. Sponsors are recognized on this website and at team events.
Local business sponsorships
San Mateo shops and restaurants can sponsor a player, host a dine-out night, or donate goods and services for our fundraisers. Thank you to Panda Express, Celia's and Jack's Prime Burgers for hosting past dine-out nights.
Ready to donate or sponsor please contact us at smsistercity@gmail.com and we will follow up.
Our exchanges run on volunteers. You can host a visiting Toyonaka player or student, chaperone a trip, help at a fundraiser or event, help with practices and culture classes, or join the board. No experience needed, just a love of the program.
If you are interested in volunteering, please contact us at smsistercity@gmail.com. For the 2027 Baseball Exchange, you can also register directly to chaperone the trip or to host a visiting Toyonaka player:
