The need for a reservation is even more serious in Tokyo because 36 million people live here. Slightly good restaurant is always full in the dinner time. Reservation at a very good restaurant usually take weeks, months, years, some of them is members-only. You can’t even get in, walk in is nearly impossible.
A reservation here means commitment. Commitment that you’ll show up within 15 minutes. A commitment of your phone number, a no show no contact may result in your phone number in the deny list of restaurant network. Some good restaurants you have to pay part of the meal or at full price beforehand. A lot of good places you would need to book 3+ month ahead with a commitment that you will definitely go there.
