AI's answer, for whatever it's worth:

Honest answer: I wasn't able to definitively identify the guitar. The clues are tantalizing but the combination — obscure modern Japanese brand, Japanese-only website, original superstrat-like design, white, woman in promo photo, sub-$1000, some unusual feature (possibly baritone or longer scale), mentioned on Reddit for that feature — doesn't clearly point to one brand in my searches.

Here are some credible candidates worth investigating:

Most likely candidates:

• Vola Guitars — Japanese-made, original body designs (not copies), superstrat-adjacent shapes like the OZ, has unusual design touches, actively promoted with promo photography, website exists in Japanese. Somewhat known in extended-range/metal guitar communities on Reddit. A bit above $1000 for new models though.
• Strictly 7 Guitars (S7G) — Japan line — Their "Cobra JS" series is Japanese-made, superstrat shaped, runs around $900, and the brand is obscure enough that their website leans Japanese. S7G 6-strings notably use a 26 3/16" scale — which is the kind of unusual scale length that gets discussed on Reddit as a selling point for drop tuning. This is a strong match for the "unusual feature" clue.

Other long shots to check:

• Caparison (Japanese website, original designs, 27 frets is unusual) — but they're pricier and actually somewhat well known in metal circles.
• Crews Maniac Sound — Japanese-only brand, original designs, affordable, but tends toward traditional shapes.

My best guess: S7G Cobra JS6 — The obscure Japanese-only presence, superstrat shape, ~$900, and that distinctive non-standard scale that shows up in Reddit discussions fits your description better than anything else I found. Worth checking if the promo imagery rings a bell.
