The Japan International Science and Mathematics Olympiads (JISMO) is an online competition in mathematics and science for primary school students, organized by Yayasan Mirai Indonesia (Mirai Indonesia Foundation). Despite the "Japan" in the name, the organization is based in Jakarta, Indonesia — "Mirai" (future in Japanese) reflects the org's branding philosophy. The competition runs seasonally, with students choosing their own test date from a set of weekly options within each season's window.
Competition format:
- Online, taken individually at home or at school
- Students select one competition date from multiple weekly slots within the season
- Offline administration available for schools that request it from the JISMO committee
- Two subjects offered independently: Mathematics and Science
