There are some really unexpectedly neat/chill pockets of Tokyo that make it absolutely worth spending more time at! That bar sounds grouse. I’ll have to see what my last few days are like, I was planning to have a go at the Shimanami Kaido from Imabari to Onomichi, spend a day in Onomichi then take a late train to Tokyo and do a wee bit of targeted shopping on my last day before flying off in the afternoon. But depending of how much energy I have, I might be tempted to be more of an urbanite and head from Takamatsu to do 3 nights in a cute part of Tokyo like Musashino or something hmmm
