About Me


Experience the most vibrant cities in the world and meet amazing people


I am working at Waseda University in Tokyo. Before that I lived in Vienna, Zurich and in Genova (Italy), and I already hosted quite some people there. I adore traveling, and I am looking forward to meet great new people and see even more amazing cities all over the world!


During the day, I am a researcher, but that is only one side of me! At nights I like to go out, for dinner or drinks with friends.

Why I’m on Couchsurfing


I have hosted several people, have met many people for coffee or drinks while traveling, and have been hosted sometimes. I see couchsurfing as a great way to meet people from all over the world and get to know their point of view and to hear the latest travel updates about destinations I want to experience.


I met many cool people through couchsurfing from all over the world. And except for one girl that nearly set my house on fire it were all positive experiences. Well, and even she did not do it on purpose :)


Obviously, traveling!!! Otherwise I like to do sports, especially swimming! In the summer, I love to go to the beach.

One Amazing Thing I’ve Done

Probably my bungee jump - it was more than 200 meters, and if I said that I wasn't afraid when I jumped, I would lie (indeed, I am afraid of height) ... so I had to do it!

If you have an unlocked phone, there are now data-only sim cards available, e.g. If you want a classical phone card with a phone number, you won't be able to buy a prepaid phone or simcard in Japan, as strange as it sounds (I confirmed that again in October 2014). If you have a 3G phone with roaming, it will work in Japan. (I have experienced several iPhones that did NOT work in Japan!) Otherwise, you can rent a phone at the airport (Narita or Haneda), and nowhere else! Or just ask a Japanese to borrow you the phone quickly when in need, they are friendly.

Copied from the forum: New data SIM - Japan Travel SIM (launched 2014-10-2) An article dated 2014-12-8 regarding Japan Travel SIM. Hope this helps.

Yamada is selling prepaid sim cards now, for example 7days for 1800 yen. there are several shops in japan, one for example in takadanobaba close to my house.

Update 15/06/2016, from a couchsurfer: "If you want to complete your description about thé 3 g i m using à rental simcard From CD Japan It s 133 yen per day for a month and really good internet."

It can be hard to find wireless internet in japan.
7eleven and the subway stations (only subway, not JR) offer free WIFI now. Starbucks offers it, but you need to register first and this cannot be done at Starbucks!
Also look at this:

How to come from the airport to my house:

The Suica card is very useful for traveling in Tokyo.

If you plan to travel around in Japan, consider buying the JR railpass. It can be bought only outside of Japan!! Have a look online!
