There are two destinations at the top of my wish list, one being Istanbul, Turkey, the other being Tokyo, Japan.
Japan is only a 9 hour flight for us, and we have thought about doing it over many long weekends from Sydney (especially since the flights to and from are overnight). Crazy, maybe, be definitely not uncommon for Australians.
There's a few appealing things about Tokyo for me:
1. Is the hustle and bustle, the bright lights
2. The cultural aspect, with the Imperial Palace and Sumo tournaments
3. The food - from Ramen, to Sushi to Yakitori to Tempura and more, so many great choices
So there's very little excuse for us not to get to Tokyo in the not to distant future. Then it will be a question of how long, where to eat and where to stay!
