Have to consider the daily 2 hours traveling time (to and fro) between Osaka and Kyoto which is no joke. Plus also the short day light duration...

It would cost minimum 1600Y or RM60 per person for the traveling expenses (to and fro) and would it be much cheaper for you to stay in Osaka assuming the reasoning for the daily travel between the two cities is due to the more costly hotels in Kyoto?

Yeah it's enough. However, be careful when using Google maps to travel to Nara, it asked me to use the limited express where u actually need to purchase a separate ticket costing ¥560 from Osaka on top of the ICOCA. I think you can use the regular trains that don't require the extra fee..

However there was another instance where I took limited express which does not require a separate fee..

Also in Japan there are various trains with similar names so have to be careful. I honestly thought semi express and sub express were the same trains and got on the wrong trains. It was my first time in Japan so I had some issues with the transportation
