Cheapest electricity provider for One room apt. in Funabashi area.

I just moved to a new apartment in Funabashi from Tokyo and it seems like I don’t have electricity here.😭 I live alone, go to college 5 days a week, and work part-time 3 nights a week so I won’t be using them all day. But I use the AC mainly when I’m sleeping or relaxing, and I also use an induction stove.

Could you suggest a cheap electricity provider that lets me apply online and start using electricity as soon as possible? Tomorrow would be fine.

I have college tomorrow, my phone battery is low, and I don’t have anyone here who would let me stay at their place even for one night. 🙇🏻‍♂️

Thank you
