Unlike USA (and Europe?) public charging infra' is nonexistent in most part of the world. Compounded by unavailability of affordable home charging devices and easy/affordable installation logistics. Toyota perhaps does not see sense in riding the 'hype', instead continue to focus on where demand is - conventional cars.
However, they seem to be investing for the future when charging infra catches up. They started on electric car tech in 1992 (way before anyone else), and continue to invest in R&D; infact had released mainstream electric vehicle - Rav4, which they discontinued in 2014 as the "charging time was slow".
Toyota couldn’t convince the world it wasn’t reluctant about EVs, in part because of Toyoda’s straight-shooting, plain-spoken approach. He (new CEO Toyoda) outlined insufficient clean energy and charging infrastructure as a “limiting option” for customers. At the end of last year, Toyoda said “it takes time,” while also noting that they’d “been investing in electrification” since they “started working on hybrids, with our sights on building BEVs (battery electric vehicles).
