Last Mon, I read in the Straits Times' Life!'s article "Dream diary whimsy" about this singer-songwriter, Shugo Tokumaru. Tickets to his show on 19 Mar have been sold out and he said to the journalist that he doesn't think his abstract lyrics (in Jap) make much sense to Jap listeners and he encourages people turning up for his gig to "imagine new scenery, lands, dioramas and lots of different colours". I cut out the article, so that I could google about his music.
Here are 2 of his music videos. Cute animation and really whimsical music. I don't know what he is singing though :)
