You have to pay. There is parking in the shopping center but you have a short amount of time and have to bring down your reciept. Its about $4 after you exceed the time.
You have one hour free if you spend more than $20 you can validate the parking lot ticket at the cashier. Weller court parking.
Not anywhere close but if you take the gold line metro it drops you off at the edge of Little Tokyo and it's pretty easy to walk in grab what you need and take a ride back. The parking that is directly under Marukai is about $9 or $10 but if you spend $25 or more they give you an hour free parking
