Since i travel slow, i can look for other option. Now going to spend whole month in Tokyo, decided to rent a room in Shinjuku-ku area, nice place, all furnished room, internet included and a kitchen, all this 900SGD per month. Did not take train pass, bcs trains to north are not running at the moment, we all know why.
So planning to do some hitchhiking when the time come.
All in all, in tokyo everything is almost back to normal
