About かずナビ (Kazu Navi)
Your friendly guide through the world of Japanese numbers, time, and more!
What is Kazu Navi?
Learning Japanese can be a daunting adventure, and sometimes it's the little things – like figuring out how to say "3 weeks ago" or remembering the counter for flat objects – that can feel like navigating a tricky forest path. As a Japanese learner myself, I often struggle with remembering stuff when it comes to the inconsistent nature of some numbers and counters, and I often find myself turning to online resources, but even the best tools like Google Translate or dedicated websites don't always get the numbers part right and they can be overwhelming to navigate just to find the right answer.
I created Kazu Navi (かずナビ) to be my personal easy look-up tool to help with my struggles and hopefully it can help other people too.
I aim to provide instant, accurate, and easy-to-understand answers for Japanese time, dates, numbers, counters, durations, and even natural phrasing, saving you time and building your confidence. While we're still in the early stages, I hope to add more features and tools to help you on your journey, the most recent being the Sentence Grammar Analyzer and the Natural Translator.

Features
Kazu Navi focuses on the practical details you need every day:
- Time & Dates:
Instantly convert times and dates, mastering tricky readings like 4 o'clock (よじ) or the 20th day (はつか). - Numbers & Counters:
Get the correct pronunciation for any number and learn how to use essential Japanese counters (like 本, 枚, 匹) with their specific sound changes. - Durations:
Figure out how to say "for 3 months" (三ヶ月間), "2 weeks ago" (二週間前), or "in 5 days" (五日後) accurately. - AI-Powered Tools (Premium):
Go beyond simple lookups! Analyze Japanese sentence grammar interactively or get natural translations for phrases across different politeness levels.

I hope you enjoy Kazu Navi!
I believe learning tools should be intuitive, beautiful, and encouraging. Kazu Navi is designed to be a calm, reliable space in your learning toolkit.
Whether you're just starting your Japanese journey (N5/N4 level) or need a quick reference, I hope Kazu Navi helps you navigate numbers and get a better understanding of the language as a whole and its natural usage. More features will be added in the future, so please let me know if you have any suggestions or feedback!
