As i had to stay in bed, i didnt see so much of Kansai main city Osaka. People seem to be really nice once again, although it seems rather common to talk to oneself (No, there was no headset, i looked). Futhermore people line up on the right side of esacalators, but tend to walk on the left in the streets nonetheless (so it actually can get even more complicated).
I visited the history museum, probably the most pointless museum i've entered in Japan so far, totally superficial explenations additionally, after multimedia experiences at places like AXA Space Center and Kagoshima Meiji restoration museum, this one gave an example of how to do it wrong. I escaped to nearby Osaka-Jo, impressive already from distance, but snow finally drove me back to the hostel to not worsen my weak condition, so all i had left was the day of departure.
