Something about Japan (contrary to common American opinion of the place)-once you get there, it's not really that expensive, as least compared to Singapore, probably even moreso with the yen situation. It can actually be true that the plane ticket is the most expensive part. Of course, if you have to stay in fancy American hotels and eat fancy American foods all the time, if you have to do ever single exclusive popup cafe or merch shop in town, or every super touristy attraction with the S tier ticket experience, sure it can add up quickly. But when I went, I took like $500 in "spending money" and ended up with a surprising amount of money left over. That included food, multiple tourist attractions, merchandise, souvenirs, etc. I stayed in a local hotel franchise and mostly ate like a local, so in the end it really wasn't that bad.
