There are loads of accommodation options for Japan. If you're on a tight budget, maybe a youth hostel is the best way to go, or maybe some kind of AirBnB type of deal. Of course, there are also plenty of 5 star options, as well as the tradition ryokan (which can also be a little expensive, although not always).

If you're looking for something a bit unique though, Japan has some great options to choose from. They're not always the cheapest though, like the Godzilla Hotel in Shinjuku, Tokyo. You're looking at around 40,000 yen per night for the Godzilla themed room. You can find a bunch of other cool hotels and their rates here ...
