Meguro Parasitological Museum
Tokyo's Uniquely Unsettling Scientific Attraction
The Meguro Parasitological Museum was founded in 1953 by Dr. Satoru Kamegai, a physician and parasitologist who dedicated his life to parasitology research and public education. Dr. Kamegai established the museum as a private institution to raise awareness about parasitic diseases and promote scientific understanding of these often-misunderstood organisms. The museum's establishment reflected postwar Japan's public health concerns, when parasitic infections remained relatively common due to agricultural practices and sanitation challenges.
As Japan's sanitation infrastructure improved and parasitic infections declined domestically, the museum's focus evolved toward global parasitology education and research preservation. The institution became internationally recognized in parasitology circles, attracting researchers and curious visitors from around the world. The museum's commitment to free admission (supported entirely by donations and merchandise sales) demonstrated Dr. Kamegai's vision of accessible scientific education. The famous 8.8-meter tapeworm specimen, removed from a patient in the 1980s, became the museum's iconic exhibit.
Today, the Meguro Parasitological Museum occupies a unique niche in Tokyo's museum landscape - simultaneously educational, shocking, and darkly fascinating. The small two-story building contains approximately 300 specimens displayed with scientific rigor and surprising aesthetic consideration. The museum successfully balances academic legitimacy with public engagement, attracting medical students, tourists seeking unusual experiences, and locals bringing dates for memorable (if unsettling) outings. The institution exemplifies how specialized scientific museums can thrive through dedication to education and embracing uniqueness.

Tips & Visiting Guide
Make the most of your visit with these helpful tips and guidelines.
The Famous Tapeworm
The 8.8-meter (29-foot) tapeworm specimen is the museum's star attraction - the longest tapeworm ever extracted from a human on public display. Removed from a patient in 1986 who contracted it from eating undercooked trout, the specimen is displayed in a long glass case showing its complete length. The visual impact of seeing a parasite longer than most rooms is genuinely shocking. Accompanying explanation details how patient remained largely asymptomatic despite hosting this enormous organism. This exhibit alone justifies visit for most visitors.
Content Warning
This museum contains graphic medical photographs of parasitic infections, preserved specimens, and detailed descriptions of infection processes. NOT recommended for squeamish visitors, young children, or those eating recently. Some visitors experience nausea or faintness. Photographs depict severe infections including elephantiasis, eye parasites, and tissue damage. The museum maintains scientific tone but content inherently disturbing. Consider your tolerance for medical/biological content before visiting. No eating allowed inside (for obvious reasons).
Educational Value
Beyond shock value, the museum offers legitimate parasitology education: lifecycle diagrams, infection prevention methods, global health impacts, treatment developments. Medical students and biology enthusiasts find substantial educational content. English labels on major exhibits (Japanese more detailed). The displays demonstrate how parasites evolve alongside hosts, complex ecological relationships, and ongoing public health challenges. Learning how to avoid infections (proper food preparation, water treatment) has practical value for travelers.
Gift Shop Uniqueness
The museum shop sells parasite-themed merchandise unlike anywhere else: t-shirts with tapeworm prints, plush parasite toys (cute versions of horrifying organisms), parasite-themed keychains, scientific books, and postcards. These quirky souvenirs make memorable (if bizarre) gifts. Revenue supports museum operations - purchases directly contribute to preservation. The tapeworm t-shirt is cult favorite among visitors. Shop merchandise ranges from scientifically accurate to intentionally humorous.
Visit Demographics
The museum attracts surprising diversity: medical/biology students, foreign tourists seeking unusual experiences, Japanese couples on unconventional dates, school groups (older students), and curiosity-seekers. The small space (two floors) often creates interesting visitor interactions - shared reactions to exhibits break ice. Popular date destination for couples wanting memorable shared experience (relationship test: can you handle parasites together?). International visitors comprise significant percentage of guests.
Photography Policy
Photography allowed throughout museum (no flash required as exhibits well-lit). Many visitors photograph the long tapeworm display. Social media posts from museum generate strong reactions - both fascination and horror. The striking visual displays make for compelling (if disturbing) photographs. Be respectful of other visitors when photographing. Some take lighthearted photos with exhibits; others maintain serious documentary approach. The unusual subject matter guarantees social media engagement.
Visit Duration
The small museum can be thoroughly explored in 30-60 minutes. Most visitors spend 45 minutes reading exhibits and processing information. First floor covers parasitology basics and major species; second floor features special exhibits and more graphic content. Some visitors rush through (5-10 minutes) due to discomfort; enthusiasts linger over every display. Plan 1 hour total including gift shop browsing. The compact size makes this easy addition to broader Tokyo itinerary.
Practical Information
Free admission sustained by donations - please contribute (¥500-1,000 suggested). Small building lacks amenities - use station restrooms before visiting. No food/drink inside. Coin lockers not available - travel light. The neighborhood lacks major attractions - combine with nearby Meguro or broader Meguro-ku exploration. Air conditioning adequate but small spaces can feel warm when crowded. Staff speak limited English but exhibits labeled. Photography allowed. Wheelchair accessibility limited (narrow stairs to second floor). This niche museum rewards those seeking unusual experiences over conventional sightseeing.
