What's New in 10ten Japanese Reader

1.28.0

September 2, 2026

• Avoid looking up text when the cursor is far off the end of the line. • Increased the maximum length of text we look up from 16 to 20 characters so that longer entries such as 東京ディズニーランド・ステーション駅 are recognized. • Made the Bunpro vocab and grammar tags link to their page on Bunpro, as the WaniKani tag already does. • Bound the number of ー expansions generated while looking up text so that long runs of katakana no longer make lookups very slow. • Recognize CJK extension characters in scanned Japanese text. • Show the popup above dialogs, popovers, and other content in the top layer. • Fixed text lookup for text nodes that are direct children of shadow roots, including scanning across adjacent inline content. • Fixed tap and double-tap handling for the lookup puck on recent iOS 26 releases. • Fixed copying an entry whose kanji headwords are all hidden dropping the "usually kana" annotation from the copied text. • Fixed some readability issues with the blue theme.

Great tool for reading Japanese

This has been a very useful extension for understanding and reading Japanese text in safari. It’s almost perfect; the one issue I keep having is that whenever you go to another page or reload the page, the puck disappears and you have to go and press the extension again in safari for the puck to reappear. If somehow the puck could remain constant until the extension is disabled, this would be a perfect extension.

Great tool, but one major pain point

The tool works really well for looking up words online. The one thing that really keeps it from being amazing is that for every new tab or refresh you have to constantly re-enable it.

Fantastic

Works very well

Great extension overall

This extension is so good I have it on all of my devices.
That being said when I use it with the Safari browser on my Ipad I have to reactivate it everytime I want to use it by taping the small puzzle piece in the search bar, even when opening a new tab. This despite being always activated in the "manage extensions" browser settings.

Used to work

The latest update has made the puck(circle) permanently on “left handed” mode without it adjusting itself to be usable based on screen location nor is it be able to switch modes(double tap).

Not only that, it’s been unable to update the dictionaries, completely removing my ability to use the tabs since mid-June.

If these two issues can be resolved, it’s an easy five star tool which simplifies the process of finding the meaning of each character.
