I did a search for Honjo on Roadbikereview's forums, and a number of threads about fenders came up. You might go there and use the search function to see if you might find some useful information. I see see a post from a local shop owner in my neck in the woods who has Honjos on his bike. He gives them a big thumbs up.
Live with intention. Walk to the edge. Listen hard. Practice wellness. Play with abandon. Laugh. Choose with no regret. Continue to learn. Appreciate your friends. Do what you love. Live as if this is all there is.
