Some of the routes cannot be reached with bus pass 600 yen and need to top up money at the end of the trip. No issue with subway+bus pass.
Hahaha. How far can you go since you are bringing the entire family?

For us, we walked on average 15000 steps per day and some days over 20000 steps. These walks also included public transports in between, food we only ate normal meals - brunch and dinner. Sometimes tea breaks after long walks and skies turn dark earlier so not many places can be visited after 5 p.m., you see nothing basically. Shops close at 8.00 p.m. Also freezing cold now, Osaka was still OK but not other cities, very cold.
Food wise, yes we had better food. Even if we save for food, not like it can be compensated for other activities, because in a day you can only do that much.

If not spend on food, where else? Activities already planned and we still visited and paid for entrance fees. Shopping is on our own expenses, so that won't be counted.
I must admit we got sick of Japanese food after few days and had Chinese food, hotpot instead.

I bought jacket in Adidas Shinsaibashi and the staff taped nicely but can't say the same for Adidas in Rinku.
Yes, my previous passport (expired already) also has staples from my previous Japan trip.
Honestly, I don't see a point for them to do it. We are not doing refund anymore because it has been deducted when we purchase our stuff. It's really a waste of resources and creates more issues (like the sharing I posted earlier).
i was rather worried when we need to remove the receipts will damaged my passport pages.. haha
japan is a country which is still not into eco-green yet. you get plenty, i meant plenty of plastic bags on every purchases you made..
