Nagaoka Raises MP Cartridge Prices Up to 31% on 1 September — and More Than Doubles the Price of Its Replacement Styli

Nagaoka & Co., the Japanese maker of the MP series of moving-magnet ("moving permalloy") phono cartridges, has announced a price revision across nearly its entire home-audio lineup, effective 1 September 2026. The increases apply to Japanese domestic pricing and cover both the cartridges themselves and, far more steeply, the replacement styli that owners buy when the originals wear out.

The figures come from Nagaoka's own price-revision announcement on nagaoka.co.jp, as reported by ecoustics.com. All prices below are pre-tax yen figures for the Japanese market.

Cartridge prices: increases of roughly 19 to 31 percent

• MP-100: ¥15,000 → ¥18,000 (+20.0%)
• MP-110: ¥16,800 → ¥20,000 (+19.0%)
• MP-150: ¥42,000 → ¥55,000 (+31.0%) — the largest cartridge increase
• MP-200: ¥51,600 → ¥62,000 (+20.2%)
• MP-300: ¥79,200 → ¥95,000 (+19.9%)
• MP-500: ¥97,200 → ¥120,000 (+23.5%)
• MP-700: ¥185,000 — unchanged

Every cartridge in the range is affected except the flagship MP-700, which carries the same price under the new schedule as the old one.

Replacement styli: several nearly double, two more than double

The more striking numbers sit in Nagaoka's replacement stylus price list, where increases run well ahead of the cartridge side of the business:

• JN-P100: ¥5,400 → ¥10,800 (+100.0%)
• JN-P110: ¥6,500 → ¥12,000 (+84.6%)
• JN-P150: ¥17,900 → ¥33,000 (+84.4%)
• JN-P200: ¥19,700 → ¥37,200 (+88.8%)
• JN-P300: ¥24,600 → ¥57,000 (+131.7%) — the largest increase anywhere in the announcement
• JN-P500: ¥31,800 → ¥72,000 (+126.4%)
• JN-P700: ¥85,000 — unchanged

As with the cartridges, the JN-P700 stylus is left untouched. Everything below it rises sharply, with the JN-P300 and JN-P500 both more than doubling.

The real change: styli are being repriced relative to their cartridges

The most consequential part of this announcement isn't any single number, it's the pattern behind them. According to the reported figures, Nagaoka has restructured its stylus pricing so that every replacement stylus now sits at approximately 60 percent of the price of its matching cartridge. Under the old schedule, a JN-P500 stylus cost roughly a third of a complete MP-500 cartridge. Under the new one, that same stylus costs close to two-thirds of the cartridge price.

That shift changes a calculation vinyl owners have relied on for years. Replacing a worn stylus instead of buying a whole new cartridge has traditionally been the cheaper route by a wide margin. Under the new Japanese pricing, that gap narrows considerably across the range, and on some models the saving from a stylus-only replacement becomes comparatively small next to the cost of the full cartridge.

Why Nagaoka says it's doing this

Nagaoka has attributed the increases to "higher raw-material and logistics costs, along with currency fluctuations," and says the revision is intended to maintain "product quality and a stable supply," per the announcement cited by ecoustics. The company has not broken out which specific materials or logistics costs are driving the change, and no further rationale was given beyond that statement.

What this means outside Japan

The price schedule described here applies to the Japanese domestic market. Nagaoka has not confirmed whether equivalent increases will apply in the United States or elsewhere, and no international pricing has been announced alongside the Japanese figures.

That uncertainty compounds an existing problem for American buyers. Per ecoustics' reporting, there is currently no publicly identified official U.S. distributor for Nagaoka's home-audio cartridge line. LP Gear's status as an authorized dealer has ended, and STOKYO — sometimes cited in connection with the brand — is listed only as a source for Nagaoka's DJ products, not its home-audio MP series. Whether or how the new Japanese pricing might eventually be reflected in whatever U.S. retail stock remains, or in any future distribution arrangement, has not been established.

What's confirmed and what isn't

To be clear about the scope of what's been announced: this is a Japanese price revision taking effect 1 September 2026, covering nearly all MP-series cartridges and their matching JN-P replacement styli, with the MP-700 cartridge and JN-P700 stylus held at current pricing. Nagaoka has named rising material, logistics and currency costs as the reason. What hasn't been confirmed is any change to U.S., UK, EU or other international pricing, or any new distribution arrangement for the U.S. market. Readers outside Japan tracking the cost of these cartridges will need to wait for Nagaoka or a distributor to address international pricing directly.
