There are a fair number of Europeans in AJX, including those from the UK, Denmark and Spain. ANA has a direct flight to LHR, so it's an easy commute. This service will be moving to HND in March, so there's a very good chance you'd be able to use Virgin instead, which has better timings for their flights and means you don't have to swelter in the sub-tropical temperatures found on ANA's flights.
