葡呑 is a Roppongi/Nishi-Azabu Japanese restaurant with a defensible niche (daily-changing menu, fresh-market sourcing, kashikiri private parties at 60% of revenue) but a digital infrastructure that has been frozen since approximately mid-2023. Your overall AI-readiness score is 35 / 100 — D, Lagging: strong product, weak digital, and the gap is fixable in 6-8 weeks with off-the-shelf Tokyo-market tools.

Your stated business goal — "increase private-party bookings + capture inbound demand outside business hours" — is directly blocked by your current website. There is no online booking widget, no English-language pathway, and no automated way for a corporate event coordinator at a Roppongi embassy or multinational to enquire at 11 PM on a Sunday. The opportunity is not to "add AI" — it's to close the gap between what your brand promises (a polished Tokyo private-dining experience) and what your digital surface delivers (a static page from before the pandemic-recovery rebuild that never came).

What's working:

• Strong, defensible positioning. "Daily-changing menu, fresh-market sourcing, kashikiri specialist" is a clear identity in a saturated Tokyo market.
• Revenue mix skews to private parties (60%), which means each transaction is larger and unit economics are likely better than a pure à-la-carte restaurant.
• Roppongi/Nishi-Azabu location naturally captures international, corporate, and high-spend demand.
• An Instagram presence indicates baseline digital awareness and a channel you can build from.

What's holding the business back:

• Phone-only reservations. Every booking — including the high-margin kashikiri parties — requires a staff member to be at the phone, in Japanese, during business hours. This caps your booking volume to "whenever someone happens to be free during dinner service."
• No English path. Roppongi has the highest concentration of inbound tourism and corporate-foreign-resident demand in Tokyo. Your website doesn't offer English. Embassy event coordinators, multinational HR teams, and concierge desks at the Grand Hyatt all silently bounce.
• Your website hasn't been meaningfully updated in roughly two years. Visitors see information that may be stale — menu, pricing, team. This shows up as a lower booking-confidence signal even when the food and service are excellent.
• No data on the kashikiri funnel. The 60%-of-revenue channel has zero digital instrumentation — there is no way to know how many enquiries you receive, which dates fill fastest, which corporate clients return, or how price-sensitivity varies by group size.
• Instagram is your only social channel. That's fine for ambient marketing but doesn't capture intent — most customers ready to book a private party are searching, not scrolling.

Technical details for your developer

If you have a developer or web person, share these specific findings with them — these are the files to fix:

1. Universal Analytics tag UA-45274937-17 is loading on every page (visible in the inline ga('create', 'UA-45274937-17', 'bunon.jp') call in the HTML head). Google sunset Universal Analytics on 1 July 2023 and stopped accepting any new data. Your website has been silently throwing away every visitor's data for roughly two years. Replace with a Google Analytics 4 property and connect Google Search Console to bunon.jp.
2. No reservation-booking widget is present anywhere on the site. Searched the HTML for the standard markers of every major Japanese and international booking platform — [a JP-leading reservation platform], [a high-end JP reservation platform], [a JP-dominant salon-booking platform], [a global reservation platform], [a popular scheduling tool], and Japanese-language 「予約」 forms — none found.
3. The site is plain static HTML (~8 KB total) with no detectable CMS or modern framework. This is fine for a brochure site but means every content update — new menu, blog post, English landing page — currently requires editing raw HTML. This is likely the operational reason content has not changed in two years.

The opportunities are ranked specifically against your stated goal of capturing inbound private-party demand outside business hours. #1 + #2 directly address that. #3 unlocks the international-tourist + corporate-Roppongi segment. #4 is the easiest revenue lever in restaurant operations — rebooked customers cost roughly an order of magnitude less than new ones.
