In one cited example of so-called kirakira (sparkly) names, it would be acceptable for the kanji characters 光宙 read as pikachū, which could be a hit for fans of the Pokemon universe. [...] As an example, a Justice Ministry official said 大空 — usually read as о̄zora (sky) — could also be read as sukai (sky). Another acceptable example was to read 光宙 as pikachū. Together, this particular pair of characters doesn't have a conventional reading. However the character 光 (light) is associated with the Japanese onomatopoeia pikapika, which refers to something bright and shiny. Together with the character 宙, which can be phonetically read as chū, a creative interpretation of kanji combo can be read as pikachū.
