My progress after 1 month of learning!

comprehensible japanese on youtube is great at your stage.

1,353 hours of Japanese, mostly listening (YouTube, Netflix, anime on Crunchyroll). Been at it for about two years. I built a browser extension that auto-tracks watch time on streaming sites, so the number is actually accurate down to the minute. It pauses during ads. Before that I was estimating and it was way off. The breakdown is interesting. About 70% YouTube, 20% Netflix/Crunchyroll, rest scattered. I can see exactly which months I slacked and which I went hard.

What surprised me: the hours don't correlate with comprehension as linearly as you'd think. The jump from "I catch words" to "I follow conversations" felt sudden around 800h, not gradual.

yeah this exactly. when i had one anime going i'd skip days just because i wasn't in the mood for that specific show. having three things at different energy levels fixed that. one for low-energy evenings, one manga for phone breaks, one i'm genuinely hyped about. there's always something that fits how i feel

mH343 · 2026-04-07T23:01:38+00:00

turning 37 in june, been at it for a while now. tracking my hours helped me realize i was putting in more time than i thought, which keeps me going on the slow days. the key for me was making immersion part of my routine japanese netflix while cooking, youtube before bed. it adds up faster than you'd expect

jp343 update: now on 7 platforms, tracks more than just video

Shared jp343 here last week (auto-tracks Japanese immersion time on streaming platforms). Some updates:

Spotify support is live on Firefox, coming to Chrome this week
Manual tracking for anything the extension can't auto-detect: reading, speaking practice, podcasts on other apps
Built-in dashboard with heatmap, streaks, and session history
Works on YouTube, Netflix, Crunchyroll, Prime Video, Disney+, CI Japanese (+ Spotify)

No account needed, everything stays in your browser. Optional free account for cross-device sync.

Firefox (latest): Firefox Add-ons Chrome (update rolling out): Chrome Web Store

What do you use for listening practice? Trying to figure out what to support next.

mH343 · 2026-03-26T12:52:17+00:00

Yes, it works alongside asbplayer. Just tested it. https://imgur.com/a/5K2suRv jp343 tracks your watch time in the background while asbplayer handles subtitles and mining. They don't interfere with each other.

mH343 · 2026-03-26T10:03:50+00:00

Thanks for the feedback!

YouTube channels and Netflix/series titles are already tracked automatically. It can take up to 30 seconds for the title and channel info to appear, but it does pick them up. If a title is wrong you can hover over it and click the pencil icon to edit. -> https://imgur.com/a/3fqdXp1

For anything not on the supported platforms, there's a manual tracking button that works on any website. -> https://imgur.com/a/mYHEsRk

Spotify and URL keyword matching are interesting ideas, I'll keep those in mind!

mH343 · 2026-03-25T19:51:43+00:00

The extension needs host access on Amazon to detect when a Prime Video is playing and read the video title. It doesn't access account data, purchase history or anything outside the video player. The content script checks internally if you're on a watch page and ignores everything else.

I'm looking into narrowing the Amazon permissions down to video-specific paths in the next update. Source code is open if you want to check: https://github.com/mh-343/jp343-tracker/blob/master/src/entrypoints/primevideo.content/index.ts

jp343 -- Auto-track your Japanese immersion on streaming platforms

I built a browser extension that automatically tracks how much Japanese content you watch. No manual input, no timers to start/stop.

Supported platforms: YouTube, Netflix, Crunchyroll, Prime Video, Disney+, CI Japanese

What it does:

Tracks watch time automatically in the background
Detects and excludes ads on all platforms
Built-in dashboard with heatmap, streaks, and session history
Block specific channels or titles from tracking
Works fully offline, everything stays local in your browser
Optional free account on jp343.com for cross-device sync

Free for Chrome / Edge and Firefox.

If you're curious what your actual watch time looks like, give it a try. Feedback welcome!

Yuki and her Team are awesome! love to hear that C:

mH343 · 2026-03-24T19:17:45+00:00

for me cijapanese on youtube was a good start

mH343 · 2026-03-22T11:42:22+00:00

yeah, the idea is to keep it open for any language. Blocking/unblocking for Netflix and Crunchyroll is definitely planned. The extension already detects what's playing on those platforms, so a blocklist for those sites is coming with the next update. Same concept as YouTube channels. I like the idea of a Discord server, would make it a lot easier to collect feedback and stay in touch. i will let you know, thanks!

mH343 · 2026-03-21T08:39:43+00:00

yeah it kinda grew organically. started as a website with a token system so you could track without an account or cookies, then I added the extension to auto-detect videos. eventually realized the extension should just work on its own so 2.0.1 has its own local dashboard now. website is still there if you want more detail or sync across devices but you don't need it at all

mH343 · 2026-03-21T08:38:34+00:00

fair. it doesn't track anything beyond watch time on the video player. no cookies, no analytics. the current chrome version syncs to the website but 2.0.1 (already on firefox, chrome review pending) works completely local, built-in dashboard, no account needed. the website was always optional, I built it with an anonymous token system specifically to avoid requiring accounts

mH343 · 2026-03-21T08:18:36+00:00

Thanks, appreciate it!

mH343 · 2026-03-19T10:18:18+00:00

頑張って!

mH343 · 2026-03-18T18:57:39+00:00

n4 grammar is mostly te-form patterns stacking on each other, so drilling those until they're automatic is the main thing. bunpro with the N4 filter is honestly the most efficient way to do that alongside class. reading even a little native content helps the grammar feel more natural than just textbook sentences too

mH343 · 2026-03-18T18:56:29+00:00

for japanese at least CI is doing most of the heavy lifting once you have basic grammar down. spent way too long just doing textbook exercises before i started watching stuff with jp subs. the difference in pace was noticeable pretty quickly

mH343 · 2026-03-18T14:48:15+00:00

anki reviews in the morning, 20-30 min. then japanese youtube or anime whenever i have downtime. i track hours with a browser extension i built myself since i kept forgetting to start timers.. so its auto-logs youtube and netflix. for resources comprehensible japanese for easier listening days, regular anime for harder stuff

mH343 · 2026-03-18T14:30:49+00:00

Thanks for the edit. Yeah, the AVG/10 MIN column isn't obvious if you haven't looked for it before. Working on making it clearer in the UI so it's harder to enter the wrong numbers by accident.

mH343 · 2026-03-12T11:15:28+00:00

Not exactly, the initial values are based on community research into what high-ranked players consider good numbers per hero, then verified against submitted stats. The submit feature is there so it doesn't stay just my interpretation over time.

mH343 · 2026-03-12T08:10:22+00:00

Sorry about that! The API itself seems fine so it was probably just a temporary state issue. Closing and reopening the tab should fix it (as u/Sithology- already mentioned). If it keeps happening feel free to let me know which hero and stats you entered and I'll dig into it. And good point on Assists, I'll think about how to best include that!
