Can Kakaku.com (TSE:2371) Justify Its Valuation On KDDI Alliance Changes?

Kakaku.com (TSE:2371) has called a board meeting for 28 September 2026 to consider dissolving its capital alliance with KDDI CORPORATION while keeping the business partnership in place.

The board meeting news lands after a strong run for Kakaku.com, with a year to date share price return of 68.49% and a 1 year total shareholder return of 52.61%. The 3 year total shareholder return of 198.50% points to momentum that has been building over time rather than fading.

The sharp rerating around Kakaku.com is clear. What still needs testing is whether recent optimism already captures the value of a looser capital tie with KDDI, or if the market is only partway there.

Most Popular Narrative: 58% Overvalued

Kakaku.com last closed at ¥3,840, which sits well above the most followed fair value estimate of ¥2,433.75. As a result, the current capital alliance headlines are being weighed against a narrative that already sees expectations as stretched.

Given the current share price of ¥3,802.0, the analyst price target of ¥2,433.75 is 56.2% lower. Despite analysts expecting the underlying business to improve, they seem to believe the market's expectations are too high.

Result: Fair Value of ¥2,433.75 (OVERVALUED)

Still, two pressure points could challenge that overvaluation narrative: profitability strain in Kyujin Box and Kakaku.com's heavy dependence on its flagship platforms.

Another View: Kakaku.com And The Cash Flow Lens

Analysts looking at Kakaku.com through earnings multiples see the stock as expensive, with a P/E of 41.1x versus about 18.8x for the JP Interactive Media and Services group and a fair ratio estimate of 27x. That gap points to real valuation risk if sentiment cools or peers re-rate.

Yet the SWS DCF model tells a very different story, with Kakaku.com at ¥3,840 trading slightly below an estimated future cash flow value of ¥3,846.30. When one method calls it expensive and another sees it as marginally undervalued, which signal do you trust more for your own framework?

Look into how the SWS DCF model arrives at its fair value.
