That depends on the type of event you want to go to! In most cases, you can purchase exhibition tickets using the ticket machine at a convenience store. (Lawson calls theirs the Loppi machine~) Simply select the name (it's easier if you have a code for it!), date, and number of tickets and print it off and pay at the counter. Easy!

With concerts and musicals, the procedure is a little more complicated! Because of limited seating, you might need to go through a lottery system to see if you can get a ticket. To enter the lottery, you need to apply online. If you win the lottery (congrats!), then you can pay at a convenience store using the method above, or via credit card if you had input the details beforehand.

You might need to join the fanclub before you can enter the lottery for some concerts, so it's best to check the details on their website :)
