Now that a suitable translation has been made for your sign, it is time to create the actual sign. Preferably, a temporary sign should be made first, so that it can be "piloted" on the job, before you spend hard-earned money to ask a company to turn your sign into an immutable physical reality.
There are many way to make temporary signs.
1) Use word or a similar word processor. You can simply copy and paste your translations into a word file, format them accordingly (add borders, word art, enlarged fonts, etc.), and print out the sign. Here are some examples.

2) Use an online sign creator site template which will format your signage automatically. These sites are available for ordering professional signage, and are happy to send you quality-made signs for a price. However, you can create your sign online and save it or take a screenshot, and then print it out yourself as in 1. Use an online sign-making website to generate your sign. Two such sites are:

These have the advantage that you can order professional versions of the signs later when you are ready to commit yourself to the sign. These companies are ready to help and will ship to Japan.
3) If you need to add labels to a template-style background, such as a map or photograph, you might not need to create a new sign at all. An innovative solution is shown in this picture (Hitoyoshi, 2014), with foreign language labels simply overwritten on already printed Japanese original maps with a colorful sign pen. This is especially advantageous in situations where customers are asking for specific information face-to-face.
