Many of you might already know that due to historical reasons, Japan uses two incompatible power systems with mismatched frequencies
That has its consequence in railways too
Meet Tokyo Central station. As you can see, western and eastern Shinkansen lines terminate here. They're not connected with each other and use different electrification depending on which part of the country the line goes to – 25kV 50Hz or 60Hz
Normal-speed lines use 1.5kV DC electrification
This small infodump was brought to you by @aroma who brought my attention to that detail
