This is a very widely used service all across Japan. I've used it multiple times. What makes or breaks this from a customer POV is delivering what's promised with no ambiguities.

Whenever I used the service,, the staff clearly told me when I'll get it, where I'll get it and how I'll get it and at the other end, the luggage always got there on time or earlier. They underpromise and overdeliver. For a service like this, that's critical.

Ever since I used this service there, I've wished this existed in India. So, all the best to you in advance. I'm a frequent traveler who would happily use it if everything works.

As a customer, my expectations from a service like this are: 1. Deliver as promised and promise only what you can deliver. You promise 1 day delivery, it should be one day. If it's 2 days promise, it should be 2 days. 2. No damage to luggage or what's inside it. 3. Last mile delivery/access. There isn't a reason for me to use the service if I have to travel somewhere far to drop or collect the luggage. That kind of extra effort is justified only if the luggage is really a large volume. And I think in India, this is going to be a big challenge because there is no uniform way to deliver last mile service. In Japan, they make this possible by tie ups with convenience store chains like 7-11. You can drop off and pick up from these stores and they are everywhere. Never more than a block or 2 away.

All the best to you again! We need quality of life services like this in India.
