Frequently asked questions
How big should a Nichirin Blade (Tanjiro) cosplay prop be?
The canonical Nichirin Blade (Tanjiro) overall length is 90 cm (2'11"), based on Tanjiro Kamado at 165 cm (5'5"). For a cosplayer who is 165 cm, proportional scaling brings the overall length to about 90 cm. Use the calculator above to get exact dimensions for your height.
What material should I use for a Nichirin Blade (Tanjiro) cosplay?
The Nichirin Blade (Tanjiro) is a mid-size prop at 90 cm canonical length. EVA foam, Worbla, or 3D-printed segments all work well at this scale. For a lightweight build, go with EVA foam over a dowel core. For surface detail, Worbla or resin-coated foam board gives a harder finish that takes paint cleanly.
Is the Nichirin Blade (Tanjiro) from Demon Slayer allowed at conventions?
Yes, as long as it meets your convention's prop policy. Most cons allow props up to 183 cm (6 feet) and require peace-bonding. The Nichirin Blade (Tanjiro) at canonical size is 90 cm, well within limits for most cosplayers. Build it from foam or similar lightweight material (no metal or sharp edges), and check your specific convention's rules before attending.
