Nice walking tour of Sumiyoshi! We enjoyed a lot! Greetings from Italy :)

I always wondered what the spare side platforms are for. Are they reserved for that planned line like the platforms at Toyosu and some of the sealed off parts of Tokyo station

Thanks for watching. This is also my query when I walk in this train station

@@TokyoDestination I hope they build this line one day.
