Core utility loop that drives initial user engagement and app retention. - **[Differentiator] Multiple Color Modes:** Categorization of visited prefectures using different colors for specific travel types. Increases session depth and time-in-app by allowing users to organize complex travel histories. - **[Differentiator] CSV Data Export:** Export of marked prefecture codes in CSV format for external analysis in Excel or GIS software. Utility feature for power users that reinforces the app as a data-tracking tool rather than just a visual map. * *User Intent:* Users want visibility into their own performance and progress. ## Market Position {#market-position} The app maintains a niche position as a data-tracking tool for Japanese travel, but its 5-year update dormancy limits its ability to compete with modern, feature-rich travel trackers. ## Monetization Strategy - **Model:** Free - **Tiers:** Free version with ad support - **Analysis:** The app operates on a free, ad-supported model with no visible IAP or subscription gates. ## 🟡 User Sentiment (Medium Confidence: 2 of 2 reviews analyzed) {#user-sentiment} - **Overall Sentiment:** Mixed ### Top Praises - **Simple scratch map functionality provides an easy way for travelers to track visited locations** ### Top Complaints (Impact Areas) - **Limited data entry options prevent users from recording specific travel details like cities or activities** ## SWOT Analysis {#swot} **Core Strengths:** - CSV export functionality functions as a data-tracking barrier for power users who require GIS integration **Growth Levers:** - Adding granular city-level logging would address the #1 user complaint and increase session depth ## Recent Changes (v2 → v3) {#recent-changes} The analysis shifted from a passive observation of maintenance mode to an active recommendation for monetization and feature prioritization. **Overall trend**: Mixed **Compared at**: 2026-08-13 ### High-impact changes - **[Added] Monetization Audit** (pricing) ### Medium-impact changes - **[Shifted] SWOT Re-framing** (swot) - **[Added] Competitive Threat** (swot) ## What's New - **Latest (v3.1.0, 5 years ago):** Added memo function and expanded language support to 15 languages. ## App Momentum (Zombie) {#momentum} - Quiet 5 years, no feature expansion. - Last major release May 2021. > **Cadence:** 1 total versions · 1 majors in last 6 months · 1918 days since last update ## The "So What?" (Strategic Takeaway) {#so-what} 都道府県制覇 - My Japan Map is a travel app that is completely free. > **Bottom Line:** My Japan Map provides a functional, data-centric utility for tracking Japanese travel, but its long-term dormancy leaves it vulnerable to more interactive competitors, so the PM should prioritize granular logging to retain power users. **Best for:** Travelers and hobbyists interested in tracking and visualizing their domestic travel history within Japan. ### PM Action Plan (Next Best Moves) - [ ] [INVEST] Ship granular city-level logging because it is the top-requested feature → increase session depth and user satisfaction ### Outlook: Mixed The travel-tracking market is consolidating around apps with social sharing and granular logging, leaving My Japan Map exposed due to its lack of feature evolution. The app's survival depends on whether it can pivot to a more interactive model before the current user base churns to more active alternatives. - 🔴 The 5-year update gap signals a shift to maintenance mode, which risks losing the user base to competitors with active feature cadences. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Total Reviews | 0 | | Sentiment | Mixed (60/100) | | Confidence | Medium | | Pricing Model | Free | | Platforms | iOS & Android | | Key Features | 3 analyzed | | Trend | Mixed | | Outlook | Mixed | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **都道府県制覇 - My Japan Map** (this app) | N/A/5 | Mixed | Sohta Itoh | | [กิจวัตรมุสลิมไทย](https://marlvel.ai/apps/th-co-mtel-muslimdailythai) | N/A/5 | N/A | Mudarmeen Munlin | | [108 Divyadesam Navigator](https://marlvel.ai/apps/com-rsunda12-divyadesams) | N/A/5 | N/A | Rajagopal Sundarrajan | | [1st Central Connect](https://marlvel.ai/apps/1st-central-connect) | 3.0/5 | N/A | Cambridge Mobile Telematics Inc. | | [2 one day trips Tokyo suburbs](https://marlvel.ai/apps/2-one-day-trips-tokyo-suburbs) | N/A/5 | N/A | mlet co.,ltd | | [360 Central Park AR NYC Map](https://marlvel.ai/apps/com-vues-360centralpark) | N/A/5 | N/A | Vadym Ustymenko | ## Company Profile - **Developer:** Sohta Itoh - **Website:** [https://tapo.tokyo.jp/](https://tapo.tokyo.jp/) ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/%E9%83%BD%E9%81%93%E5%BA%9C%E7%9C%8C%E5%88%B6%E8%A6%87-my-japan-map/id1562358991?uo=4) - **Google Play:** [View on Google Play](https://play.google.com/store/apps/details?id=jp.tokyo.tapo.jpn&hl=en&gl=us) - **Dev Site:** [Official Website](https://tapo.tokyo.jp/) - **Sources:** Developer website content, App store metadata, User reviews. ## Related Intel Reports - [*กิจวัตรมุสลิมไทย*](https://marlvel.ai/apps/th-co-mtel-muslimdailythai) (Mudarmeen Munlin) · N/A Rating - [*108 Divyadesam Navigator*](https://marlvel.ai/apps/com-rsunda12-divyadesams) (Rajagopal Sundarrajan) · N/A Rating - [*1st Central Connect*](https://marlvel.ai/apps/1st-central-connect) (Cambridge Mobile Telematics Inc.) · 3.0/5 Rating - [*2 one day trips Tokyo suburbs*](https://marlvel.ai/apps/2-one-day-trips-tokyo-suburbs) (mlet co.,ltd) · N/A Rating - [*360 Central Park AR NYC Map*](https://marlvel.ai/apps/com-vues-360centralpark) (Vadym Ustymenko) · N/A Rating - [*360 LA Los Angeles AR Map*](https://marlvel.ai/apps/360-la-los-angeles-ar-map) (Vadym Ustymenko) · 5.0/5 Rating - [*360 NYC: New York City AR Map*](https://marlvel.ai/apps/com-vues-360nyc) (Vadym Ustymenko) · 4.0/5 Rating - [*360 Tampa Bay AR Map*](https://marlvel.ai/apps/360-tampa-bay-ar-map) (Vadym Ustymenko) · 5.0/5 Rating - [*3HStay.com: Booking Hotels*](https://marlvel.ai/apps/3hstay-com-booking-hotels) (ABS Software International Sdn.
