Hi guys if I were to plan a airasia flight arrival at osaka and departure from tokyo, I need to book 2 one-way ticket?

Any downside of that other than the more expensive fare?

Yup that what I did initially, but it leads me to kiwi.com which has pretty bad reputation according to reddit, just wondering is it the same if i purchase 2x 1 way tickets

Is uniqlo and muji that much cheaper in japan? I compared online prices seems like not much difference?

So the Japan store price and online price differs?

Thanks guys will visit Uniqlo once I reach there
