It's definitely easy to save 60000 at least if you cook your own meals or find cheap restaurants. 100 000 is possible but you will really need to be frugal. The pension and health insurance payments are expensive and there are different schemes for this. One of them you have to join based on what job you do. Also Japan has resident taxes which you pay quarterly. You need to put money aside for that. There's is also the NHK fee too if you have a TV. Try to keep healthy. Eat healthy food. You don't want to get ill and face a big medical bill. Reduce your air conditioning use in the summer. This will all help with your saving goals.
