yes, you can receive sms for reload BigPay sms

you need list down train(with & without pass) & flight price, then you know which should take

i will suggest take train without pass
tokyo to kyoto, 14110 yen
kyoto to osaka, 560 yen

take a stop in nagoya if you have extra days, tokyo > nagoya > kyoto > osaka

JR pass already cost you 28110 yen for 7 days

flight is cheaper, but don't forgot there is a cost from tokyo city town to tokyo airport, and osaka airport to osaka city town, & carry with your BIG luggage.

Bus is the cheapest i believe

1st way:
most popular way is wait for AA free seat promotion

2nd way:
the cheapest fare in AA is buy from AirAsiaBig using app, but normally is final call sale, promotion update every week(some is 2/3 weeks) Monday time 00:00
it can cheaper than AA free seat promotion, but can't guarantee the date you want.
i get my jeju 300+ return flight, and 700+ osaka return flight using this promotion
you need at least 1000 point to redeem the flight in AirAsiaBig app

3rd way:
another one is using AA voucher, through RinggitPlus website apply credit card, last month is RM350 AA voucher, This month is public bank RM200 AA voucher
and each booking allow you use up to 5 vouchers, which is RM1000 discount.


note : unable to use AA voucher in AirAsiaBig app
