Inquiries via the form
The dedicated English form is displayed below. Complete the relevant fields and submit; the general inquiries desk receives the message and routes it to the appropriate person.
General inquiries
If the form is not convenient—for example, you need to attach files or continue an existing email thread—write directly to contact@sggroup.jp. The same general inquiries desk receives both channels.
02 — What we receive

Operational notes
Response hours and reply times
Inquiries to both the form and the general inquiries mailbox are reviewed during weekdays, 10:00 – 18:00 (JST). The standard reply target is within two business days of receipt. Messages received on weekends, public holidays or during extended seasonal closures are handled from the following business day.
Depending on the subject, additional business days may be needed for internal review, transaction matching or technical investigation. Where a substantial delay is anticipated, we may first send an acknowledgement and follow with a substantive reply.
Attachments & confidential material
This form does not accept file uploads. If specifications, proposals, screenshots, images or other files are required, submit the form first and continue through the reply email or the general inquiries mailbox. For an existing matter, continue the existing email thread where possible.
Do not send passwords, API keys, seed phrases, card numbers, expiry dates or security codes, identity documents, unnecessary third-party personal data, unpublished trading information or highly confidential material. If an NDA is required before details are shared, provide only a high-level outline in the first message and state that request.
Financial-tool and customization scope
Financial tools, templates, reports and support provide information, calculation, visualization, analytical assistance, record-keeping and document support. They do not provide personalized investment advice, trading signals, instrument recommendations, entry or exit instructions, order execution, asset management, forecasts or guarantees of profit or performance.
Within an eligible plan or separately quoted engagement, we may accept non-advisory technical or functional customization of display items, general formulas, template wording, export formats, UI, analytical-support features and public-data imports. State the objective, current environment and required deliverable in the message.
Handling of personal information
Information received through the form or general inquiries mailbox is handled within the purposes stated in the Privacy Policy, including responding to the inquiry, verifying the person, transaction or contract, maintaining related internal records, necessary communications and service improvement. Submit only the minimum information needed.
What we cannot accept
We may decline to handle or reply to messages falling into any of the following categories.
- Unsolicited sales outreach, templated bulk pitches, mailing-list offers, SEO outreach, backlink or reciprocal-link proposals and unsolicited guest-post pitches
- Requests for individualized trading decisions, entries or exits, stop-loss or take-profit instructions, instrument selection, portfolio allocation, capital-management instructions or guaranteed outcomes
- Messages containing credentials, secret keys, payment-card data, identity documents or other confidential information that this desk does not need to receive
- Unlawful activity, content contrary to public order or morals, infringement of third-party rights, attacks or threats against SG Group or others, or inappropriate language
- Repeated identical submissions, automated send-outs, false information, impersonation or other nuisance contact
