Who Wrote The Song 'I Can Do It' Used In Anime?

Honestly, the phrase 'i can do it' is such a common song title that without the anime name it’s a bit of a guessing game. I’ve tracked down songs used in shows before and usually the composer is listed in the ending credits or on the soundtrack single — sometimes it’s the series’ OST composer, sometimes an outside pop songwriter, and sometimes a character song written specifically for a CD drama.

A quick trick that always helps me: take a short lyric snippet from the clip, search it in Japanese (if the anime’s in Japanese) and add the words ‘single’ or ’OST’ to your query. That tends to surface the CD info or a reliable database entry showing the 作曲/作詞 credits. I love that little investigative part — finding the name behind a tune makes the scene stick with me even longer.

Let me cut to the chase: 'i can do it' by itself isn’t enough to name one songwriter because that exact phrase appears in multiple tracks across different shows and albums. I’ve spent plenty of afternoons cataloguing OSTs, and the same title can belong to very different songs — one might be an instrumental bed written by the show’s composer, another a pop single licensed for an ending, and yet another a character song written by a third-party songwriter.

If you’re trying to identify the writer for the version used in a specific anime, I’d check the ending/insert credits first. Next, look up the anime’s soundtrack on VGMdb or Discogs where composer and lyricist credits are usually precise. When the song was released as a single, the CD booklet lists 作曲 (composer), 作詞 (lyricist), and 編曲 (arranger). Keep an eye out for in-house composers — many series have recurring names — but don’t assume it’s the same person across different shows; popular composers like Yoko Kanno, Yuki Kajiura, Kenji Kawai, and Hiroyuki Sawano get a lot of recognition, yet smaller series often use lesser-known writers.

From my experience, the most reliable route is the official soundtrack or single notes; fan wikis can be helpful but double-check against primary sources. Finding the writer turns that catchy line into a neat little victory for your music library.

I tend to answer this quickly when friends ask: there isn’t a universal single writer for every song titled 'i can do it' used in anime. Titles are repeated a lot, and the songwriter depends on the exact show, single, or OST you heard. The practical trick I use is to check the show’s end credits first, then the soundtrack or single’s jacket for 'lyrics' (作詞) and 'music' (作曲) credits, and finally an online database like VGMdb or the Japanese rights database to verify.

Often the performer is not the songwriter, so don’t assume the singer wrote it. Also watch for covers or licensed pop songs slipping into anime; the original songwriter will still be credited. I like tracing these credits because it leads me to discover favorite composers and arrangers who pop up across different series — it’s like following a thread through a whole music scene. Keeps things interesting, for sure.

I've dug into this kind of thing a lot, and the short version is: there isn't one single person who wrote every song called 'I can do it' used in anime. Titles like that get reused a lot, and who actually wrote a particular track depends entirely on which show or soundtrack you're talking about. When I want a definitive name, I go hunting through three reliable places — the episode end credits, the CD/OST booklet (if one exists), and databases like VGMdb or JASRAC — because anime music credits are usually very explicit: lyrics by, music by, arranged by.

If the song you mean is an insert or an ending theme from an official series, the composer/lyricist will usually be listed in the single or on the soundtrack. Sometimes it's a well-known anime composer, sometimes it's the singer themselves, and sometimes it's a production house staffer who rarely appears elsewhere. There are also cases where an English-language pop song titled 'I Can Do It' gets licensed into an anime; then the original pop songwriter gets the credit. For me, the fun part is tracing a song from the tiny onscreen credit to the full CD jacket credits and then to the songwriter’s other works — it’s amazing what you discover about arrangers and recurring collaborators. If you ever spot that credit, you’ll usually end up finding a neat chain of creators behind it — always satisfying to see a composer’s signature style once you know their name.

That little phrase 'i can do it' turns up in a surprising number of songs, so the short truth is: there isn’t a single definitive songwriter unless you point to a specific anime or scene. I ran into this exact confusion a few times while trying to track down insert songs — sometimes it’s an original piece by the series’ composer, other times it’s a licensed pop song with a completely separate writer.

If you want to know who wrote the one used in a particular anime, the credit you want to find is usually listed as 作詞 (lyricist) and 作曲 (composer) in the ending credits or on the single/OST booklet. Official soundtrack releases, VGMdb entries, Discogs pages, and the anime’s own website often list full credits. Streaming services sometimes show songwriter info too, and community databases like MyAnimeList or AniDB will often link to the single where credits are visible. In some cases the performer is actually a character voice actor and the song is credited to an in-universe pseudonym — that’s when liner notes are gold.

I’ve chased down obscure insert songs by cross-referencing clip timestamps with soundtrack tracklists and reading Japanese single notes. A practical habit I picked up: search the anime title plus the Japanese lyric snippet in quotes — that usually pulls up the single’s page or a reliable forum thread with credits. Personally I get a kick out of uncovering who crafted the music; it makes rewatching that scene feel even richer.
