I visited the Shimano Bicycle Museum two years ago and it was a delight. Their new museum is even better than the one they had about a decade ago (smaller building inside the large Daisen Park nearby).

When I purchased the ticket I was offered an English version of the history of bikes presentation in the main hall. I politely declined, but was later politely approached with a piece of paper handwritten with a time the English version would play. I attended and was so glad I did. It was a beautifully presented showcase of bikes across history (with individual bikes in the room being thoughtfully-timely lit up as the video described them).

Really worth going. And I super love Japan and the way I've been treated wherever I went. I've been to Japan about a dozen times now over the last 20 years - it's my favorite place to be.
