Assuming from my own - pretty nosy - nature, I thought it would be fun to share what I spent all the money on, during my trip. Since I stayed a month in total, I'm sure a certain amount of cash was used to feed and carry myself around. There are only two or three days I recall, when I didn't board a train during my 4 weeks stay.
However, I got the chance to buy a lot of stuff - though I couldn't help my thrifty nature and didn't spend nearly as much as I feared I would - and especially the 100¥ shops, namely Daiso were to my liking. I still don't understand why we can't have something like that where I live.
Literally everything there was more pleasing to the eye than what I've seen for easily twice as much in my home country.
The quality might not be the best and I have to admit that some of the stationery I bought are decrepit by now (after one year of constant use), but other things from the same store still work completely fine.
