As previosuly mentioned, they’re starting at Keisei Ueno station. There’s not a lot of Street View around this station, but there’s two and a half thousand photos attached to the location, so let’s see what we can turn up.
First panel of page Title+1
Elevator! Escalator!
券売機! (Looks like they’ve updated the map since this chapter was written - Keisei Ueno is now on the left-hand edge. Ticket price to Nippori is still the same, though. I did, however, find this page with a photo of the old map.)
Ticket gates (Kind of impressed they can pass through at a run without missing the ticket coming out the other side.)

Train interior
This appears to be a photo of the Haku-Dou station platforms, but it doesn’t quite resemble the glimpses we get here.
Meanwhile, the lines of three companies meet at Nippori station - Keisei, JR and Toei - meaning there’s close to five thousand photos, so it’s a bit tricky to pick out anything that shows up here…
In any case, that was a nice little tutorial on how to buy train tickets in Japan.

What do my home and the Colors hideout have in common? No air conditioning.
Yeah, but your home is probably not a corrugated iron shed. 
Bit of a step back this week after all of the exitement of catching a train last week.
Being back home for the holidays, I’m mostly just jealous of the Colors’ weather at the moment… 
(Just remembered that Japanese Language is actually Googleable) 
Wow, how do you live? It’s -10 here and I already don’t want to live anymore haha
Curled up by the fireplace, treating it as a deity, mostly.

This week, it’s family time デース.
I was genuinely expecting Kotoha would burst at some point during this chapter…
This was a super fun chapter.
We had a “home corner” in my classroom when I was about 7 which had dolls and a play kitchen and that sort of stuff for us to play “families” in, and this chapter really reminded me of the storylines we used to come up with 
On a separate note, since next weeks chapter is the last one in the volume, I’ve read ahead this week because I’m trying to finish a few books before the new year starts

Final chapter of the volume!
When they suggested she write a 未来日記, I admit I was kinda picturing something just a little further into the future than half an hour.
