When I still commuted for work (western 23-ku initially and later out towards okutama), I had a portable wifi, power bank, water, a protein bar or two, a book, sunglasses, folding umbrella, sunscreen, noise-canceling earphones, and ibuprofen in my bag (in addition to work stuff or whatever for that daily activity). Being stuck on a train that loses power makes one prepare.
Now, I love in the inaka and work from home. I really should throw some water and calorie mate in the car, though, as I think about it.
I often still do. In japanese, google even became its own verb (possibly because it works phonetically and syntactically) both as google-suru and google-ru (グーグル)
