日本が大好きだけど、ここで日本語があまり見られないから、新しい区分は必要じゃない。
As a native Japanese speaker I can tell your Japanese is very fluent! Strictly speaking, there exists the Japanese local board but no child boards, so the request is adding child boards for Japanese local board. While I agree Japanese community is not that big, I do not think Japanese community is so small compared with other local communities that have child boards as well as local moderator:
| Language | Posts | Topics |
| 日本語 (Japanese) | 29485 | 137 |
| Eλληνικά (Greek) | 31322 | 2333 |
| Hrvatski (Croatian) | 20875 | 1035 |
| العربية (Arabic) | 15169 | 1641 |
Note that the the number of posts and topics in Japanese board are data after the massive elimination of altcoin threads. It seems to me that it is not unreasonable for Japanese community to have child boards.
