A little-known travel app that is Airbnb-meets-Tinder helped me have the wildest night in Tokyo partying until sunrise

CouchSurfing is an online community that connects travelers with locals for free lodging.
I rediscovered the CouchSurfing app on a trip to Tokyo, Japan, last year.
Instead of using the app for lodging, I used its "Hangout" feature, which is like Airbnb-meets-Tinder. It helped me meet locals and have a wild night out.

When you open the app, CouchSurfing encourages you to "Travel Like A Local." Instead of opening on potential places to stay, CouchSurfing now opens on "Hangouts."

To use Hangouts, you simply turn on your availability. You can either start your own hangout by typing in what you want to do, or browsing the hangouts other travelers have already started in your area. In Tokyo, there were a lot of options.

Each Hangout has a person's profile and what they are looking to do. Activities range from simple things like grab dinner or beers to "visit Tokyo Metropolitan Art Museum" or "attend an underground rave in Bushwick."

Once you join a hangout, you are entered into a chat where you can arrange the plans or just get to know each other. Best of all, multiple people can join hangouts so "grabbing beers" doesn't turn into an awkward date if the person turns out to be a dud.

On the night I tried it in Tokyo, I noticed a group talking about going to see the ambient rock band Tycho at Stellar Ball, a concert venue in Shinagawa. I decided to join up and headed to the venue after work Friday night.

I found the CouchSurfers gathering near the bar at the back of Stellar Ball. Tycho hadn't started playing yet so we got to know each other.

Some of the CouchSurfers had arrived solo, but many had brought friends with them. It was a mix of a few Tokyoites with varying English fluency, a couple European travelers, and one other American traveler, a chatty Army vet from Texas.

To my surprise, only one had ever used CouchSurfing to stay at someone's apartment while traveling. But all had been using the app to meet up with people regularly.

Within a few minutes, a few more locals joined the group, meeting up with the woman who had organized the "Hangout." The woman worked at a Japanese e-commerce site with the locals, one of whom was American but had living in Tokyo since graduating college.

All in all, it was a pretty seamless experience. Tycho was excellent, one of the CouchSurfers had snuck in a bottle of shochu that we passed around, and before long we were all lifelong friends for the night.

After the concert, one of the CouchSurfers suggested we head to an izakaya they liked nearby.

The izakaya was on a narrow alleyway in Shinagawa, seemingly in the back of another separate restaurant. It would have been an impossible place to find on my own. And the restaurant didn't even seem to have a menu.

It didn't matter. One of the Japanese CouchSurfers ordered a few bottles of beer and

We caught the last train of the night around 1 a.m. and headed to Sangenjaya, a maze-like locals area of pubs, shops, and tiny restaurants.

One of the organizer's friends — not a CouchSurfer — wanted to go to his favorite bar in Sangenjaya. I hadn't heard of the neighborhood before, but it looked just like the yokocho, or narrow chaotic alleyways, that I imagined made up Tokyo before I arrived.

After spending most of my time in Tokyo's clean and sterile business districts, seeing this side of the city was a welcome change.

The bar we went to was a place one can only find in Tokyo — and which I will probably never find again.

Tucked deep in an alleyway, the host pointed out a narrow door and directed us upstairs into an impossibly small bar.

There was barely enough room for two or three people to stand in front of the bar, which was no bigger than a kitchen counter and the sitting area made New York apartments look spacious. No one was sitting, anyway. The tables had mostly been pushed to the sides and a raucous group of a dozen Tokyoites were taking turns loudly belting karaoke tunes.

Every minute or so, the entire group shouted "Harmonica!" and the bartender stopped what he was doing and did a short harmonica solo, before pouring more drinks.

Our host told us that the very drunk man singing was the owner and the bar's gimmick was as you paid for one drink, you could drink as much Jägermeister as you wanted for free.

Needless to say, we stayed the whole night.

The people singing karaoke were pretty good, particularly the couple that decided to do a Japanese language version of "A Whole New World."

WholeNewWorld-Tokyo

Once the other locals realized that there were two Americans present — the Army vet and I — they decided we should sing American songs. Without asking, they put on Red Hot Chili Peppers and handed us microphones.

Twenty or thirty songs later — including "Wonderwall," "Semi-Charmed Life," and "Don't Stop Believin'" — we realized it was 5 a.m.

The group mostly dispersed, but the host took the other American and myself to her favorite ramen spot to end the night (morning?). I took the first train of the day back to Shibuya and fell asleep. Thanks, CouchSurfing.
