I won't be surprised if they replace beer with yellow colored water to save money by cutting out the fermentation expense.
All of mitchmu's snark aside, it's always been my experience that they cater local beer at the outstations. So you will almost definitely have Japanese beer ex-Asia. ex-NA to Asia, if there are some leftovers in the cart from loading up in Japan they will have Japanese beer but I wouldn't count on it.
Also, sake is free in Y on flights to/from Japan.
