Karaoke in Japan are serious business, they are open to wee hours in the morning and Japanese loved their singing. Karaoke bars in Japan are unlike the ones in the West, here everything is quite professional. They have a public area, if you like to sing with a lot of people watching you or you could have a private room, enough for you and your friends. Now if you are alone, no problem at all, they have rooms small enough for just 2 person.
Limited availability of microphones may be in the West, in Japan you don’t have to worry about it, they do have plenty and they will provide you with more if you want. In Japan, you can find Karaokes even in the most remote areas and in the city, there are lots to choose from. Now make sure you check out the prices of your karaoke room before settling down, there are some that charges for every 30 mins and others by the hour. Some provide soft drinks the entire night as long as you order their snacks while others don’t.
I usually go for the food & drinks plus the company but some people go there to get drunk and if you look around, these Karaokes are frequent by all class of people. From business men to school kids. In the afternoon, Karaokes are much cheaper – so if you don’t want to spend too much , check them out in the afternoon.
