Actor Daniel Radcliffe says he is learning to speak Japanese but is finding it tough.

"I just started learning Japanese. It's super hard, but fascinating," femalefirst.co.uk quoted the British star as saying.

"My favourite word so far is tokidoki (which means sometimes) -- it sounds like 'okeydokey'," he added.

The "Harry Potter" star also speaks a bit of Spanish after being taught at school, but he believes the only reason he passed the language exam at the age of 16 is because he mastered the accent.

"I passed my Spanish GCSE (the UK's General Certificate of Secondary Education] thanks to my accent skills. My grammar was absolute crap," he said.
