From their website:

Join us July 24 - 27, 2025 in Mercer, Maine for four days Celebrating Japanese Woodworking!

This year we are expanding from 3 to 4 days, starting with an all-hands group timber frame raising and continuing the tradition of in-depth, hands-on workshops, expert instructors, opportunities to learn and practice with Japanese tools, and special events including a Japanese boat launch ceremony, swordsmanship demonstration, BBQ Bonfire Party, and of course the revered planing competition!

See their website for full schedule and details.

JSB members can get 7% off any of the workshops or individual festival days (the festival bundle packages already have discounts) using code on the member only portal.
