Tadeusz in Japanese

Tadeusz is written タデウシ in katakana. Katakana is the script Japanese people use for foreign names, so this is how Tadeusz would appear on a Japanese ID card, a café cup or a name tag. Depending on the origin of the name, it can also be written タデウシュ (as written in Japan) and タデシュ (as written in Japan).

Our top pick is 建羽詩 (Tateushi). 建 means “build”, 羽 means “feather” and 詩 means “poem”. Other good options are 建宇詞 (Tateushi) and 建佑信 (Tateushi).

Not as a traditional name. Japanese people write foreign names in katakana, so 建羽詩 is a creative kanji spelling (called ateji), chosen for its sounds and meanings. Japanese readers will understand what each character means, and many will enjoy the idea behind it.

建羽詩 has 28 strokes in total (建: 9, 羽: 6, 詩: 13). It takes some practice to write neatly, so look up the stroke order before trying it with a brush.

Each character in 建羽詩 has a positive meaning, so it is a reasonable choice. Keep in mind that Japanese people will read it as the meaning of the characters, not instantly as “Tadeusz”. If you want your name to be recognized, katakana (タデウシ) is clearer. Either way, ask a native speaker to check the final design.
