Reiko Kobayakawa keeps a verified Twitter at @reiko_kobayakawa, where she posts on upcoming projects, shares behind-the-scenes material and occasionally replies to followers; she uses it mainly for announcements and community engagement. On Instagram she runs @reikokobayakawa_official, with a curated selection of photo spreads, personal snapshots and previews of her work. The account is public and accepts direct messages for professional inquiries, though reply times vary.
For closer access she runs an OnlyFans under the same name, with exclusive videos, private messaging and early access to new releases; details and pricing are on her profile. She is also on FanCentro, where users can buy personalised content, request custom videos or book paid consultations. The link to her FanCentro storefront appears in her Twitter bio and Instagram story highlights.
For formal proposals, magazine features or event bookings, she is represented by the agency T-Powers; inquiries should go to their office email, listed on the agency's site under the talent roster. She does not publish a personal phone number or direct email, and all legitimate business correspondence runs through her management for privacy and security.
She receives fan mail through a postal address managed by her agency, available on request via a direct message to her verified Twitter. She does not accept gifts or packages sent to a personal residence and asks that any physical mail go to the provided PO box. Digital messages can be left as comments on her Instagram posts or sent by Twitter DM; she reads and replies to a selection, though she cannot promise a response to everyone.
