How expensive is Tokyo at the moment? What would one week cost there?
I just spend a month in Tokyo, my serviced apartment was around $2,700. Daily lunch via Uber eats was between $12 and $25.
Going out for beers would be from $5 to $11. Eating out also just varied, but usually eating at local restaurants was probably around $15-$20.
Public transport was pretty cheap, usually between $3 and $5. Took a taxi late at night a couple of times, averaged around $25.
(This is all with the current exchange rates)
A quick check looks like $80/night is about the minimum for renting a serviced apartment in Amsterdam. I recently moved from Japan to Europe and everything except groceries feels 1.5 to 2x more expensive.
Ah groceries are on the rise here too; in part due to rising prices of e.g. meat due to factors like avian flu and more awareness of living conditions after "exploding chicken" (broiler chicken) tanked the prices as low as €3 per kilo (with liquid injections etc). Dairy products are up as well, cheese has gone up by 2-3 euros per kilo, butter by another euro, etc. I think milk is subsidized though, it's been fairly consistent.
(I work in Tokyo, btw.)
My 2BR furnished apartment was $1,500/month with 3 different subways nearby, 2 train stops away from Shinjuku. The company I used is Fontana and I can highly recommend.
When I visited three years back you could grab ready-to-eat food (by item or a pre-made lunch) from a supermarket for under $5. Japan can be very inexpensive.
