The first thing you will have to worry about when you arrive in Malaysia is ``communication methods''. The traditional method of changing your SIM card while receiving instructions in English at the SIM counter at the airport is now a thing of the past.
If you use eSIM, all you need to do is set up your smartphone while you are in Japan. From the moment you arrive at the Malaysian airport, you can use the internet right away.
eSIM is a technology that allows you to add a data plan directly to your smartphone without a physical SIM card. Almost all modern smartphones, such as iPhone XS and later, Samsung Galaxy S20 and later, support eSIM.
