The Tobu 80000 series (Japanese: 東武80000系, romanized: Tōbu 80000-kei) is a commuter electric multiple unit (EMU) train type on order by the private railway operator Tobu Railway in Japan.

[5] The trains use a SynTRACS variable-frequency traction system incorporating synchronous reluctance motors (SynRM), a first for major private railways in Japan.

[6][5] Unlike permanent-magnet synchronous motors, SynRMs do not use rare-earth magnets and allow for simpler circuitry.

[4] In light of declining ridership on the Tobu Urban Park Line following the COVID-19 pandemic, Tobu Railway decided to reduce train capacity (from 6-car sets to 5-car sets) instead of reducing frequency.

[5] The 80000 series is scheduled to first enter revenue service on the Urban Park Line on 8 March 2025.
